4, "mountain bike" in terrain

Understand the basic characteristics of various terrain to enhance self-confidence, but the driver needs to practice in drivers.

Stonehenge

Meet larger stones, best avoided, from next round. Want to jump over it, to see whether behind stone has enough space, whether born bicycle safety. If the bike at a slower speed, stone and more big, need special cycling skills. Considering the game close to slow speed when some stones, until the obstacle over again after speed. Also should choose power transmission ratio is big gear. General crankset and flywheel chooses medium.

Small stones

The so-called small stones, size ball size. But, bicycle riding on it. Therefore, be full of small stones terrain for all the drivers is a daunting challenge. Meet the terrain, control and brake are very difficult to bike, must grasp the corresponding control car skills.

A very important fact is perhaps we should not forget most. That is, in be full of gravel or cobble ground control bicycle in hard on the ground texture. Therefore, on the bus, drivers must loosen all over, according to the circumstance, flexible, not "handle" bicycle, but "guide" from a bicycle is hard to compare the place where a hard. To be successful, riding process must choose one place, then blunt past, aim. If you want to change the direction of cycling, driver just need to take the barycenter moving from one side of the body to the other side, then gently push bicycle in a certain direction.

The habit of braking also needs to be changed. Hill, body weight, rear back to gain greater friction. Before using too often, brake, especially when turning. Don't make the friction between front and ground is too big, to maintain the proper. After using as much as possible, with less former brake. Otherwise, the bicycle into rocks or cobble can skid. At this time, not only can slow, instead of bicycle, thus accelerating lose control.

ravine

Through to the ravines, as far as possible to maintain level. Bicycle If you are stuck in a ditch, light person can hit a bike, the person can damage. Small groove can jump over the past, if the ditch is wide, need to think another way. If the width of the ditch, can also ride from the past or. Front GouYan encounter when the body weight, the left front back and then push front to ditch. Wait to opposite of slope, in front and brought out from the ditch. Body weight forward, to continue the stirrup. This is a skill and across the skills of the big stone. However, here to do not jump from obstructions on past, but from or out.

By water erosion gully and V type is relatively difficult terrain. This communication ChangKuan 50 centimeters, also in 50 centimeters. The simplest way from the ditch above only carry bicycle. Besides, there are many methods. Best method is to use in front when crag to balance stunt. When the rear body gravity met or slightly forward, and continue until the stirrup, out of or.

If the bicycle was stuck in the trench, need to find a place to ride out the little gradient, also can use side qi fa jump out from the groove. However, if the ditch is too deep, slowly, bicycle to slow climb out later.

The sand

The sand often allow the driver to tremble, but with the terrain of skills and covered with sand and gravel performance of terrain. Meet the terrain, bicycle front easily trapped in the sand, the driver also hard to control the direction of the bicycle. This is the bike in the common techniques can correct operation of the following:

With the fastest way possible target location near the sand, and moved.

Smooth force, keep speed of the stirrup. From the comparison of loose sand is thick, be like in through the same surfing, gently "prey" in the past. Tip: don't forget, other cyclists and motorcyclists through comparison, riding up where your lungs.

roots

Roots for many drivers, it is evil, especially in the slope, the driver must be mix. In such cases, or is carried the bicycle, or use front from the ground up front, balance, followed by special focus from books, let the rear roots above roll over. Please remember not to increase power transmission system, otherwise, it will reduce the friction pressure.

log

Like stones to treat logs, use the same cycling skills. The only difference is in the rear of logs, met the moment, must assure front has fallen on the other side of the log. At this time, the body must not be too. Compare the logs can use qi fa jump technique jump.

Across the water

The water from a very exciting place through the affirmation, but to do so before the water depth, a see whether there is water stone or pit. Even very understanding the terrain, the links are not may be omitted. If you don't understand, or have long time no pass, better slow down, or simply walking past off. Use the famous sports authorities dropped the abbot's words: "because of the water and mud speed and braking effect is bad, and carry on the bike, the best bike from water, walking through the wet shoes, still can do." However, if the very confident, think oneself can safely through, then let courage be blunt past, but must be put back the body gravity.

3, "mountain bike" in downhill

The body relaxing. When the bike riders, only if the stiff limbs and his bike will likely also meeting next turbulence. Drivers should take next crouching posture, legs and arms slightly bent, hip gently sit on the seat. Do not only can improve the speed, the driver can still feel very comfortable, in order to better control of bicycles. Drivers on the body, after a center in the saddle, can make the frame after the activity space increases, thus can absorb a certain impact. The seats lower 3-4 centimeters, this also can increase operating space. All staring at the driveway, rather than road barriers.

High-speed, short downhill

In this cycle, the driver slopes designed to look at, so you can choose a direct bottom line. This is very useful, because in the whole process of terrain, as long as downhill, bicycle allows can achieve the fastest speed, slope rushed over to maximize accumulation momentum. Such doing can maximize the preservation, in order to improve the whole strength of average speed. In this sport, the driver's main goal is to choose the appropriate hill slopes, and washed route across the line, and then stick with it.

Long downhill

Long downhill, namely to choose to compare easy to deal with the terrain, also need to grasp the corresponding cycling skills. In this process, the driver could not glance from top to bottom, so in the whole process of total should be observed while walking. According to visual ahead, cycling speed; 15 meters far ahead of the ground, at least heed terrain allowed to place sight. Choose to walk along the route, and then down this route, but don't forget to adjust the terrain change at any time. This sounds a bit difficult, but after some time on the ride, you won't have too big problems. Begin to choose, can certainly easier with speed. Do not force too fierce, speed, don't be too quick, otherwise, will soon feel exhausted, sparking a crash.

Technical downhill

Without understanding the terrain in front, before the downhill fast speed should not. Drivers need to familiar way, so what obstacles to safety and walk around. Even in current terrain familiar, but recently rode in here, especially the recent weather, driver also should be carefully observe terrain, lest more dangerous accident happen.
Professional athletes usually is dropped in the driveway on lap, and then try to handle an obstacle, until he found the best bike route, and then the confidence. A good advice is in the game, on the whole journey before in a general impression, but also remember us all about the relevant skills and various tips. Technical downhill, must take alternate protective equipment, such as special helmet and gloves, protective clothing and protective shorts etc.

The glyph downhill

The glyph generally include a series of downhill movement, and does not include short downhill slope climbing over again. Therefore, the driver must control speed, so as to cope with hairpin and other various. The most popular sport in the cycling skills are drawn out of the way before the corner, but need to consider every journey distance, so as to prompt the brake and success. In bend brake is never allowed, on the one hand, which would seriously affect the ability to cope with difficult terrain, On the other hand, the focus of the driver may also transfer from the bend, this high speed to bend to cross.

2, "mountain bike" in breaking climb

Mountain bike ride in the mountain is in motion, thus breaking up the sport became the indispensable part. Apart from being a strong body and enough strength, correct cycling skills also helps drivers successfully handle various downhill. Bicycle can drive forward and upward movement, depend on two key factors: one is the motive power of transmission system operation and the size of the wheel and the ground, the friction between. Operation of power transmission systems with the size of the strength of the body with the driver and the size of the strong power is directly related to. With cycling skills, friction bicycle tyre types and the barycenter position and drivers body pressure on the tyres.

The steep hills, texture soft light stone road and low friction

Ensure that the bicycle in the process of breaking up the secret has been moving forward to make drivers of body weight distribution, cycling posture, the size of the strength of the stirrup, and the coordination between the best route to achieve the best state.
The weight of the distribution in steep climb is difficult to climb, and the slope, and some drivers to adopt standing posture, it in the quality of a material is solid, friction is working on the ground of large, but in the typical cross-country, the situation is different. At this time, ride skill shows its important role. Drivers should try to put the body to the rear seat shifting, increase the pressure on the rear wheels, thus increase friction. But to do so, the curl up front easily, cause bicycle is difficult, and economical up over there may be back. If the focus, not from the front and rear, but there may be in soil is soft ground in situ, the results of a bicycle idling.

Cycling posture considering the factors mentioned above, the driver should according to landform after adjusting the position of body gravity at any time. In order to make the body weight, the optimum distribution throughout the rider may just sitting ass gently seat in front.

The size and strength of the stirrup way to drive forward movement, drivers must bicycle for smoothly toward power system transmission of energy. If the force is too big, have the potential to reduce friction, Strength is too small, and may have slowed down, or cause bicycle to stop. And if, instead of fierce pedaling smoothly make circular motion, wheel pedal will do with the ground because of friction between the decrease in situ sliding, idling.

Technical climb

Climb steep slopes in comparison of various rules apply equally applicable technical climb. The only difference is the technical climb break need not seek appropriate drivers specially, as long as you can ride on drivers, ravines or abrupt muddily rutted between root out a road. Visual ahead of 5 meters, ground chooses the best lane. However, once the cycling route, do not get optional change.

Long climb

The general rules of the sport of cycling in specific rules are applicable, but according to the degree of difficulty of the terrain and the size of the slope. However, in order to be able to ride completely, drivers must of strengths, select the appropriate speed and gear transmission ratio. Want to conquer all the slope, need drivers fit, large enough strength, master the skill and cycling is to adopt a correct attitude movement.
At the beginning, some drivers body is not strong, still cannot cope with certain kinds of slope. However, through enough exercise, the situation is capable of improvement. Just started training, don't put targeting the whole mountain, will start from the place to handle, then gradually to the difficult step. In addition, still remember, just can achieve the goal, don't care when. If you have confidence that we can conquer most slope, need to consider speed.

How soft soil, and comparison on steep slopes of newly launched a bicycle

Once the bicycle in slope stopped and a new start not easy. Car drivers must take steps forward, backward, or a new, choosing the appropriate locations. The place is flat, must be large, for example, a friction is flat rock. At the same time, the choice of transmission ratio is not too big, can cope with gear is the current situation. If it is too big, bicycle and may be broke down. Choose appropriate gear, using the power of the largest, most of the leg feet move bicycle, hold the bicycle brake, etc, the forward movement is on the other foot pedal, then stable strength, speed, until the return reservation driveway. Another good way is the bicycle in the driveway inclined, then put the car started off.

First, the "mountain bike" in how the fell to the ground

Drivers in cycling process if fall, will not only hurt yourself to feel embarrassed, also. If the cautious, and remember some simple rules, in most circumstances can avoid wrestling, at least, can reduce the damage to a minimum.

A, early parking. If just ride to the top of the hill, suddenly appeared a serious erosion gully, be full of the slope, and a stone was designed with the pit, if it ran down too fast, too, the body has to stop immediately sideways, paper and fell to the ground. Doing just have several small scratches, if rushed to or straight, then the wounds which is difficult to estimate.

B, limb, body curl up into the fold, with rolled on the floor. Although do not so easy, but encountered situations, don't panic. Need to remember that one is not the arm outstretched to support yourself, don't fall, because such word limbs are most vulnerable. Let the whole body under the body into force, a ball (like judo class teacher), can guarantee the body does not hurt too heavy.

C, keep the original momentum. Coming down, do not force struggled to keep the original thrust, continue to carry forward when riding until fall again. The body landing, paper roll forward, until finally can stop. If the emergency brake, tyres may be torn up, injured drivers will inevitably. Of course, if you are in the slope steep cliffs or run down, you must stop the bicycle left no stone unturned, meanwhile, to find something that can stop bike.

D, let bicycles absorb certain wallop. Sometimes, can let bicycles for yourself down, and also conveniently as pad. Broken bike can change, but if the injured person, can not so simple.

E, jump down from behind the bicycle. Bicycles will fall, if is in decline, but also not process to remedy, so riders can loosen the bicycle, jump down from behind. The bike will eventually stop, and reduce weight, because there may be causing damage to any component, the most important is I can avoid hurt. Driver

F, down don't shoulder touchdown. When I fell down on shoulder must be broken collarbone, even worse. If you find yourself with the object is near the collision, please forward or backward to fall, so, we will not be on the shoulder.

Crashed car security in response to the Road

Typical low position taxiing: because racers knew when turning range is too big and turned his head, can make the car around the flag pole, so he let it fall to the rear brake, then, in complete control of the car under to grass.
Caution: can completely open fractures to prevent fall when the wrist injury or cause of clavicle fracture, but must clenched his fist, arms bend! Don't use straight arms landing.
Typical measurement rolls: "High Siding" refers to turn over body from the outside, have the car. The knight in collision ground, arms and shoulders, and bending over his head in the car, tumbling is not the car collision until the danger.

At high speed, hit the barrier of the mood will slow motion to the ground. When a car and a car over fears of body parts, zhi were more deepened heart afraid, but the impact, every bone rattler, this fear is too true! Let knight can not help but ask: is it possible to prepare for the fall down? Practicing simple car can reduce risk fall? While riding mountainbike often broken, but if we are rolling in high-speed learning can be careful when hitting the ground to reduce the strength or learning from on high ground and soft can reduce the risk of injury and should be. Here is our experiment proves feasible, after some skills.


A: even CheDai people skills together
In most situations, as far as possible in the best car longer, because bicycles don't feel pain, than the body easy car repair, so as to protect themselves by the first line of defense, to resist trees, stone and other bicycles for bodily harm. The car had hit every thing will slow speed, if drivers tumbling drivers are warning, rather than give off all fall, is usually not seriously injured.


Skills: the principle of inertia
When BMX knight leap to the air, into their car, sling and make a wonderful posture, always admirably. Once the unfortunate fall, face down on the ground was bad enough, if the car again let fall onto face, must be disastrous consequences. So, if you can safely or will put forward when the driver turned away, must take the car.
In the cliff edge quickly fell from the runway at? If the brain is fast enough, turn off the cliff edge the reaction, will you body brilliantly runway. Of course it was a rescue, but quick thinking and the inertia of the physical principles can save your life.
Skills: low position by taxi


When the car is unable to stop when the rear locking, and turn and make the car DaHeng, can let slip out of the car. Then use the inside of your feet on the ground, as to support drag stability. The taxi driver control in the correct position, intentionally let body lay low position can prevent your taxi drivers, also have over can prevent you off cliffs. But in the flat and hard soil practice this skill. When the car in your body gliding, control under handlebar and try to use your feet to the inside of the taxi stopped.


Skills: four measurement rolls
Find a piece of soft mat or a bunker, then head, with one diving headfirst one shoulder roll, finally stopped by hand. In the first after tumbling, will focus on one side, and then bent arm, until she stops. First in static state by jogging speed, action after skilled subduction, can let you off at high speed, keep a small car.


Five: clench fist techniques, protect the wrist
Wrist wrist is the most important part of the mountain bike, but it was injured, are the hardest to treatment. If you handle opened slipped backwards, wrist injury, thus will fold, therefore in the wrist bump into the ground, hand to hand clenched, so also can protect the skin on the palm and wrist. The best is measured in automatic pumped when rolls.


Skills: protection of clavicle fracture
You can withstand the pressure of clavicle tyre pressure. Basically, they like to prevent the rope under the shoulder. If fall down from the time, in order to stop and completely unbend arm, and will make his collarbone. Your arm will drop power transfer to your little clavicle, clavicle compression will like a piece of bread as great break. Then you to the hospital, and spent a lot of money after his collarbone, such as heal itself, even after recovery, you will also have a shoulder ahead, it is not. In order to avoid broken collarbone, please read the skill 4, trained measurement technique. Rolls


Seven: careful skill is best
Want to hurt? So try to ride on a steep, let foot pedal, then leave the tube, and live in the trunk hit, your body will turn handlebar and feet will be shaking off in your mountainbike after the very. In you from the steep and unable to control the rapid slide, grasp and brake pedal, slips, a better side, then focus is going from the rear seat cushion, skidded off the bicycle), can jump from the safety car or can be made low dumping car until the security posture glide.

Mountain Bike Downhill Technology

This article from the part of the BRAIN works LOPES, this book include some downhill, jumping, turn and trampled and vehicle handling skills, is very good reference books.

"No matter you are a newcomer, or an expert, you are inevitable to the problems encountered downhill, even three world champion LOPES is not exceptional also, especially for slippery, have roots and the stone pavement, but he can always find the way to deal with, let us see what he is some magic weapon?
1 set: some players found vehicle slope is a very troublesome, from the vehicle's setting can see BRAIN, here to give you some advice: I like short, with the rise of the Angle, and with little litres of curved (only), appropriate to downhill, Reduce seat, change is strong, in addition, the big change is thick tubes is right choice.
2: in the field, and even downhill end use hard, the frame of the fork travel long could bring good feeling, make you more simple, my hill is to use the Suggestions about four inches (about 100-120), oil spring structure is a good choice. In setting, besides the rebound damping according to different road conditions in different choices, the hardness of the fork, need than normal setting in the hard, so that the violent collisions, ride for fork will have enough space.
3: in wearing, if you need to practise earnestly, you alone downhill should dress for the standard, not to clash on behavior standards (safety is always the first topic) bicycle
4: see, the far far: the attention, you can't downhill below, you wheels, you should pay attention to in front of you, you should see you after a few seconds to ride, it helps you to adjust speed corners and advance with shock and etc.
5: stand under the broken, or advise you to adopt standing posture, so the body absorb more conducive to you from the end of the car hard unable to absorb shock, of course, if you are in a relatively flat surface, or said before you face a nasty turns, you sit down, to facilitate your body weight in the wheel, have better tour of trace.
6: appropriate clutch, someone says, when the downhill to relax, my hand is also don't put too loose, otherwise you can't cope with sudden shock. (proper grasp, and follow hunch and don't try so hard, the movement and give him any control),
7: appropriate use your legs and cushion, leg is not to trample, also is not used to sit seat in the bottom slope, especially when you leave the cushion, had better use your legs and the cushion to control your car balance and body posture, and move your focus more on the hill, and choose a strong, handy (comfortable, but will not affect your hair force cushion)
8: do not often use brakes, with great speed when you enter the mud, leave your hand brake, mud itself has provided enough resistance, keep your front direction of body gravity. Enter in front.
9 whether or not to jump? Had better not jump, lifelike, most of the time, it will affect your speed and dangerous, but sometimes you have to jump, such as when you face a series of roots and sad when the stone.
10: wetlands marching in wet road is a very sad, pavement condition and body posture is very hard to predict, stone and roots in the road, you need to reduce the maximum stress round of sideslip (reduce power distribution), the direction of the most difficult is that you need to use your brakes master prior to use, and know when to kill and master, all depends on your speed with the speed of the terrain, and you need to come from experience.

Basic bike riding skills

A bicycle riding skills, basic


(a) posture


Correct posture is: the teaching of cycling, low head slightly sloping forward, Arms bent down to the waist, natural bow down, reduce the body weight, and prevent and car jolted due to force. Hands light and powerfully wrap, hip sit tight seats.


(2) the stirrup


Cycling of the stirrup methods have freestyle, toes down and heel down 3 kinds.


1 and freestyle stirrup method: at present, some outstanding athletes are mostly adopts the stirrup freestyle. This method, the stirrup is in the process of rotating feet in a week, according to the different parts with changing ankle angles. Freestyle stirrup, accord with principles of mechanics, the direction of rotation and pedal formed circumference tangent consistent, reduced the knee and thigh action is helpful to improve the amplitude, frequency, stirrup naturally through critical area, reduce the blocking zone. A thigh muscle also can get relative to relax. But this method is more difficult to grasp the stirrup.


2, toes down the stirrup method: its stirrup is in the whole process of the stirrup spin down, this is her ankle range, small method is helpful to improve the frequency, easy to master, but the leg muscles always is in nervous condition, against nature through critical area.


3, heels down type stirrup method: heel downwards stirrup type is slightly upward and downward tiptoe heel 8-15 degrees, this method is rarely used in normal riding in just a few people in riding process for excessive use of force to adjust when heel downwards stirrup type. It is characteristic of the muscle in short time change, hard to restore short rest, muscle fatigue.


Second, turning skills


(a) : a car is inclined to bend, incline.


1, based on the car body gravity to bend inclined, people in the same car maintain Angle.


2, the knee unbend of lateral and subconscious overtime, like you to put your feet trample down like (but if you really beat him down don't find us).


3, with a knee medial beam, this is an adjustment of the track you good method, reduce stress can narrow locks.


4 and lateral hand pull a handlebar.


Using the two good timing tilt:


Can use the curve is not less than 45 degrees) (accelerated


You can clearly see front but not familiar with the bend


Wet asphalt road, tilted two defects:


On a rainy day, although the turning skills can give you a good traction, but it's Angle and the weight of the distribution and arrangement not conducive to wet road, No corresponding inclined skills more sensitive to reverse.


(2) : the car to the upright position within the body, to bend inclined.


1, move, until the nose and brake into line.


2 and keep the car body bent to erect, within the lateral enough to tilt (arm unbend)


3, a CeWai handlebar to bend.


4 and the arm elbow bend inside and outside also handlebar back to turn out the arm handlebar handlebar direction.


5 and keep both knees buckled, continue in cadence.


Third, the bicycle ride downhill


Downhill rides on the road cycling technique is an important basic techniques.


(a) uphill riding technology


To maintain the normal uphill riding the stirrup action, not sudden force, in the ordinary circumstances, unfavorable use standing type riding bike or tiras type method, otherwise you'll be excessive consumption. Meet them short, should make full use of the motion inertia principle, easily and quickly to the coping of the stirrup can be used when the speed of riding, stand, to improve speed possible downhill to create favorable conditions. Meet the long, according to their physical condition adjusted ratio, don't wait on motionless and speed completely change ratio, lowered to resolutely to avoid to start the phenomenon to appear. What a long or a steep, can alternate stand, adjust pin type parts, let part muscle forcibly rested.


The uphill with not too near. Due to the reasons, driving up with cars, often swinging too close, may collide. Furthermore, the uphill speed significant decline, the car will make himself with the method of riding restrictions.


(2) ride downhill


Downhill rides to achieve the ideal effect, be brave to wit, brave talk, concentrate, two eyes close watch of the road ahead, ready to appear on the surface treatment of the determination of any situation, Not only should make full use of the car, and motion inertia glide to active the stirrup, increasing speed.


Turning to the body, and to maintain consistent, in his car, and keep a straight line, the centrifugal force to overcome. According to the speed and bend Angle, but generally size shall not exceed 28 degrees, otherwise have slipped.
Before turning to control the speed. With the gradual deceleration, brake method, and at the same time, the gate as far as possible, a former gates ahead before using the front gate, direction and the direction of the car is consistent, otherwise, the meeting because of the rider, weight, and restricted to the inertia of wrestling. After the corner gate will go, lest cause unnecessary. After using the corner gate don't too. Otherwise, the car could turn or slip.


Four, brake technique


Before you can provide very good braking force, but also can let you become frequent flyers, below we tell you how to brake.


(a) before using it will focus back


When you use the brake, you before the inertia and natural gravity will forward, you must practice when you start braking, consciously will you move backward (body low, bottom back). Focus back, the more you can use more brake force.


You can be in the sand or a bit wet flat floor exercises, speed, using different force under the pressure of you before and after the brakes, know how to control your brakes. Or ask ace when riding in the use of how he brakes.


(2) before turning to reduce power of brake


And in turn to drive a car, you must reduce speed. If you turn on the hard ground when you brake, you will lose control of sideslip produced. When used at the same time in the corner of your before and after the brakes to reduce your speed. When your front brakes will reduce the response, so reduce the braking power before you turn will be more perfect.
If you are in a downhill, need to use the hairpin, try to use the power of the rear brake. As in the last minute, flat on the front to reduce weight back behind 30% of brake force, 70% for brake.


(3) not excessive pressure before brake


"The inertia is your friend," you need to go through the rocks and the speed of obstacles. Otherwise, the wheels would stop turning into your hand will have. Excessive pressure before you can make checks, and under the car.


If you turn on the steep slope before use, then you must also brake control of your brakes and not overly has been forcibly, when you can according to a press release a braking action to prevent locking brakes phenomenon.


Five, mountain bike skills -- simple techniques make you more like the professional rider


Riding a bike with you family and children, shower in the suburb of nature, enjoy the trip. One or two things may be around you: or in the procession, mountain bike you hungry want out something to eat, but when you go hand in hand bicycle is easy to fall, Do you want a drink of water, you are like a far from you to get, When you watch rear, don't worry about that, through our after these tips, as long as a little practice, you will be very skillful, seem to be born and ability.


1, why? If possible, find a flat, or is slightly downhill road, the road uneven (not a good time to handle loosened, don't stop pedaling), and keep looking at you, not the hands, one elbow, holding hands slightly curved. Elbow slightly bend can absorb shock of stone pavement, and stable in any effect when you drink the movement direction of mountain, another hand down the kettle, then, also can't see below but keep looking ahead, so constantly practice repeatedly, until the very skilled. If your canteen is small, reached down, to grasp it, if the cap is large, then hold the bottle of bottle of local, the water in the kettle to corners, lest side cover. With teeth unplug caps, after drinking, using your body to shut up, then bottle closures smooth land back on the shelf, still cannot look down, keep straight ahead. If this recruit, let's take a bottle, or try not to use a water system, as long as a straw in the mouth.


2, looking back, you can leave the hand hand, should pay attention to the road ahead, when you look back from left shoulder twist, will you hand to relax, the elbow, although slightly bend your upper body torsion, still can keep the direction of straight, mountain, if you ride very fast, you can also quickly from your left arm down quickly check below. If you need to compare long time to check, then you must sit is near, right at vertical tube, and then go left the tap, present a body torsional look back on, a professional skills: when you ride with another man, when you go back, sitting up and touched you ride with the shoulder, this will help you ride a straight line.


3 and if you intend to ride a bike more than a hour above, it is necessary to some pockets of clothing made by natural food can enhance physical block food, of course, you may use both hands to eat a meal, you can only eat the food that simple packaging. In the anterior, you shall tear of packaging are some, such as you eat the unnecessary expend setbacks. While these food placed, the best is very easy to get the sack and not mixed together with the map of the deep pockets, take up very convenient. When you're ready to dine, body, and a sitting beside hand vertical tube elbow part, leading to reduced shaking slightly curved, then took food and tore down your earlier part of tear down, then can eat. Remember, eat and do not lose skin, should be put in the bag.


4 and the wavering rider in groups of riding is dangerous, even individual solo in a crowded, also can endanger others when. If you are not sure of his ride a straight line, so you should be in the white paint line along the line to practice. But if you can relax and upper arm, the simple exercise is almost impossible, so must be relaxed. Will you hold hands light slightly curved handle, elbows, about 30 feet on the vision, but don't focus on line, as long as you know in this line, and soon you will find himself very stable.

Bicycle Drift Cheats

Bicycle light climbing skills

Whether you have faced in hill-climbing maneuvers to overcome obstacles? Climb the heart rate, muscle pain, climb up, the HuTianQiangDe posture deformation... Relax, yet fully established in power, all again before beginning from the correct posture will make you more easily when climbing faster and!
Head,
Must be able to raise head at the front road, avoid by all means is low head "drudgery", not only will have security problem, also can affect your breathing.

abdominal

When the output is not climb abdomen, but in fact plays a role of abdominal support when climbing, is when a stretch of abdomen feeling, this is the upper abdomen in support of the output, and play the role, the balance of power in the abdomen in climbing the pose when knights of balance, should be in response to any fadeaway stretch sit-ups, reinforcing the regional power.

seat
In the proper height of seat cushion, seat cushion position before finding the cock cushions and how much is very important, generally speaking, seat cushion center in the rear gear disk axis, but it's position is because of the person different, must try, on the other hand, seat cushion of tilted in seat cushion most front end to a level as a benchmark, seat cushion of the saddle to conform to the shares, then knight each brand cushion under different degree and concave, but also to users to adapt.

knee
As far as possible when trample on knee climbing on the position near the pipe, so the next step trample action can use to the thigh of the lateral femoral muscle, and if you will trample away from his knee in the frame, doubtless is wasting your strength.

palm
When you stand long-distance climbing in the palm, getting position should hand change positions will be easier, want to hold down the general like Pantani posture to climb ahead is not easy, because the focus more on the back of the bending stress is bigger, plus the head Angle breath is not easy, and holds the posture climbing only under attack by comparing the.

Station appearance

Use stance ride hill-climbing purpose has several: 1, 2, and a steeper slope when attacking your opponent position 3, let other muscle relaxation, Imagine you are running, but the bicycle is beginning to step forward in step to the bottom, also must pay attention after dead point to the output to also want to maintain the balance, this is the biggest difference with running.

Back,
Keep back to the back of the plain, and abdominal muscle under lateral force, if the muscle that you can't get back to nature into flat, then you may choose a small frame or too short.

Chest,
Keep in the chest, tightening as you when fluctuation stair general nature, tightening of chest will disturb the diaphragm and because affect respiratory, reduce the energy conversion efficiency.

elbow
Keep your elbow slightly bent forward, when leg power can parallel output, pull back and let your body and efficient actuator, Station appearance when trample, the hand movement, and later became feet above the power to make separate turns output.

hip
Musculus glutaeus maximus is the largest human body, and extends to the thigh muscles to climb, after sitting here, if you can use when the muscle will be more efficient, the output is and you cannot rely on chair leg strength by the feeling of similar to stand on the bike, in the capacity to do so, must pay attention to again after the action, but must tick with high cushion, lest hurt and heel of Achilles tendon.

In fact, there is no secret to climb the training, but the road bike in hill-climbing strength is the best moment in climbing, each rider is applied, the condition of cardiorespiratory function in the power, the al-maktoums, while climbing a ride the training process of muscular strength and cardiopulmonary function, must according to the established, and this is used to light or heavy gear ratio and the fast or slow trample rotary training course, the steep or slow... Most of all, a relationship, but in the use of the body when climbing over ten parts as detection, can help you ride at a good foundation.

Bicycle maintenance guideline

Do you still remember you are riding your car on the street, exciting sprint, If you are thinking about sitting at home, cycling, but found out of your car, performance, it is no longer as the brake less sensitive, it's no longer so smooth transmission performance, ride it, all of her voice, If you ever found in the field, your car is unable to continue riding, you must walk 20 kilometers of road, pushing car son home. For the bicycle users unless you have a problem to every car, it will be lost, and buy a new one, otherwise the maintenance and repair bicycles are not avoidable, On the other hand, maintain good car in getting the failure of the machine rate, also will decrease. Here introduced bicycle maintenance technology, are common, and can DIY (Do It Yourself).
General maintenance of bicycle, can be divided into the following kinds: normal riding use, After a week or ten days) short term (regular maintenance, Medium-term (one or two months) regular maintenance, Long-term (half an year or one year) regular maintenance, Wild emergency repair
In this � � divided according to time, as in daily to cycling twice a week on the above situation to the use of the bike, if you are riding the lower frequency, or your bicycle is frequent, then can use the time to adjust, pp.1 near to suit different riding condition.

Tools
� � so-called sharp tools make good work, must carry on the bike, using the correct maintenance tools is a must, if use inappropriate tools, may cause the difficulty on the job, and even bicycle parts of the damage, so below for general maintenance of tools used must be an introduction. Necessary basic tools

Wrench or open-end wrench: generally spelled r-e-g-u-l-a-r could purchase, open end wrench use more convenient, but must notice when buying more commonly used bicycle for metric bolt, But a wrench, in many work is a must.

� � hex wrench: general metal can be purchased, pay attention to the general use for the metric system.
A screwdriver: there is a word with cross two metal, can be bought.
� � removed when the outer tire pole: remove use, can be in store for car.
� � repair glue and repair piece: with, can be in the car repair shop.
� � dozen chain: remove chain.
� � steel wire wheel wrench: adjust ZhangLiYong circle.
� � lubricants: is not a tool, but is necessary when maintenance, to prepare the butter and oil, and generally chain lubrication oil three.
� � special tools (non-essential, but have the best)
� � socket wrench: use in the disassembly crank fixed bolt, generally for 14mm or 15mm.
� � crank remove: used for removal of crank or big gear disk.
� � chain sprocket wheel wrench: will the decomposition.
� � flywheel remove: will the flywheel, removed from different manufacturers use the flywheel must use different disassembly.
� � HuaGu wrench: for the open end wrench, thin flakes to decompose HuaGu axle and bearing, generally for 13mm 16mm to.
� � fork thin sheets of bowl wrench: used for loading and unloading, open end wrench, adjust the fork bowl of different size fork bowl.
� � rubber hammer stuck to knock the parts:, make its loose.

� � workbench: used for maintenance, bicycle up.
� � adjustable wheel rims steel frame: adjust tension.
� � third hand tools, used to live in the skin, adjustment brake when braking very convenient.
� � wash clean chain chain: use very convenient.

Normal riding
� � normal riding use is not need any technical, but in the dimension of bicycle, protect the most important and the most basic one in riding bikes to bike before, is very important, is often forgotten, therefore, remember to do before the bike in the following check:
� � check riding position size: if you ride in his car is exclusive, remember riding before seat cushion to appropriate height.
� � check each part of the screw: check and firmness of seat cushion between quick check whether the lock, whether drivers already fixed, other screws are loose.
� � check tyre: check whether the tire pressure, the insufficient enough pressure to appropriate checks whether the womb, wall cracks have appeared, cut the tread pattern is already through shallow, if necessary, to be replaced tubes.
Brakes: try � � check before the brakes, check whether can really "brake brakes.
� � check fork bowl: before the brakes, will halt the front and back, as there are shaking the gap, shaking that must be readjusted before fork bowl.
� � checking transmission: after the start first try to change speed and before respectively after speed, whether can smooth change to the speed, whether there will be strange voices.
Short-term regular maintenance

Tire size and rim size with the

The size of the bicycle tyre phyletic and confusing. Worse, in the early stage, each country according to oneself

The size of a nominal system manufacturing bicycle. These different countries size nominal methods caused such a situation, namely

The same size of tyres in different countries have different digital identification. The most troublesome situation are not interchangeable use the phase

With the size of the tire often have the same number identification!

2 / traditional size system
According to the size of the traditional system for measuring the outer tire. This method is often in inches for unit (26 ", and "etc

Etc), or with centimetres (650,700, etc.).
Unfortunately the tyres and circle the development of measurement method not tally with the actual situation. Let us look for? Why

X: 26 will in late 30's is a heavy "balloon tire (ballon trucks)" the most popular sizes, the bicycle

Until today, the size of the beach in "cruiser)" uh cruiser (this car is also common. The size of the wheel

The actual diameter tyres and 26 inches very close. However, some of this kind of tyre is not satisfied with the rider, they want more light faster

The tires. Then industry will create a "medium", its nominal size for the tyres, 26 (1.75 can apply the same circle

. Although they are called "26 inches," but the real size is the tyres May 25, rather than 8 inch / 26 inches. The same

The size of the circle by west klunker pioneers, and became a mountain bike. In the market, you can

Find the mm with the tire that narrow circle, and the use of 26 inches tire its actual size is almost 24 July/August.


The second Numbers or letters that the width of the tire coding (26, 27 x x 1.75 1 1/4 650B, 700C...).

3 / "0.75" mean "three-quarters"?
Please note the nominal sometimes use of inches width (26 (decimal said), and sometimes use 1.75 score (26 (1)

3/4). This is the most common cause of don't match. Although the nominal size in mathematics is equal, but they are

Are different sizes of tires, this is not swap. Want to summarizes the characteristics of tire dimensions is suspended,

But I have confidence to put forward the following rules:
The brown tire dimensions:
If two tyre mark in math equal size, and use a decimal another use of the score, then the two

A tyre can exchange use.
Sometimes the tyre manufacturers in this issue even made many. Especially in some European model also mark the wrong, they should make

In decimal nominal but mistakenly used scores.
4 / size of fraud
Competition often leads to broadband measurement error. The following reasons: if you are the market for high-performance 700 x 25 tires, you might through the investigation and the catalogue manual light 700-25. If the Pepsi company and delicious tire company tires have the same quality and technology, but PepsiCo 700-25 tire is actually 700-24 tyres for 25, so only nominal the Pepsi than Coca-Cola company real nominal 700-25 more light. PepsiCo has such a competitive advantage. In order to prevent the Coca-Cola company and they will be even more light 700-23 logo for the 700-25.
This situation in the 1970s and 1980s, later development to unmanageable, hence again return precise width

Measurement of the trend (but not very common).

5 / ISO (E.T.R.T.O.) system:
The international organization for standardization (ISO) established a set of common tyres, in order to eliminate all kinds of size system. This system had been called "E.T.R.T.O" system, is the technology of European tires and wheel rims European Organization (in) with needed and Rim.
ISO system using two Numbers. The first is the width of the circle, tires, or in millimeters. According to the actual broadband tire (the width of the circle is a little change of the width of the measurement is. Circle circle of the distance between the edge.
The second ISO digital is a key figure, is the diameter of the circle hub, the unit is mm. Generally speaking, if the number is same, tires, can install to circle, If the number of different, tire Ann doesn't go up.
For example, a 700 * public road tires for 20 - the ISO nominal geotechnics, A mixture of 700-38 womb for the ISO nominal 38-622. The width of these differences tyres doesn't suit exchange use, but any suitable one circle of tires with other models can also use the tyres.

Although you can practice any use of the same diameter wheel tires/circle "combination", but using the difference is too big
But very unwise. If in a wide circle used on a very narrow tires, may have damaged the risk of leakage and circle. If you are in a narrow circle on the wide use of tire, may have side circle circle or the risk of failure. Unfortunately, the risk is at the edge of the mountain. In order to reduce weight, the circle is too narrow mountain nowadays. This narrow circle with wide tire, unless a very bad breath of filling the tires very full. But it was lost, and the wide circle to the side of the improper pressure exerted.

Simple way to measure the width of ischial

ALLAY cushion available, a number of foreign Ju You also want to buy.

However, there is no local measurement of the width of the memory of silicone between the ischial seat.

We want a simple way to measure the width between the ischial, and riding in the afternoon and colleagues who carried out the experiment.

After a 2 5 times the test result is accurate, and silica gel cushion measurement results more than 5 ~ 10 mm.

This is ALLAY memory silica gel saddle, and the above requirements to measure the width of ischium time, probably in the back and horizontal lines 80 ~ 85 degrees.

As required, to find a stool to sit well, and then placing it bottom below, it is easy to feel the ischial where a part of the finger to determine the location of ischial, and then bottom up, measuring finger contact position of the distance between the ischial . Will be able to arrive at inter-ischial width.

Can also sit to one side when the right is the edge of the ischium, ischial with a finger to come to another location, and then measured. Of these methods measured the width of a slight deviation of the ischium, but very small.

We measured several times, the data measured than with silicone pad for extra 5 ~ 10mm.

Ju You can mail-order ALLAY seat, you can click the above methods to measure the width of its own ischium.

Then choose the corresponding size of the cushion.

Some people say that the best choice for V brake is a lightweight, but the disc's easy to feel it is better than those offered V brake, of course, can not ignore the price difference between the two; disc how to choose? What's the difference between the two? Which you fit?

 

For which you have brakes?

V brake groups:

Beginners: Simple good maintenance, adjustment, adjustment easy, inexpensive supplies, absolutely handy for beginners.

Travelers: disassembly easy, quick assembly and maintenance simple and most suitable for use when traveling.

Lightweight mad: Weight tapping, affordable, choose the V brake absolutely can reduce a lot of weight.

Racer: a low failure rate, repair rapidly, many players are still fans of V brake it!

 

Disc brakes groups:

Visual system: Emphasize distinctive appearance, vision on behalf of all the charm of the absolute disc can not be blocked.

Than the series: equipment class people do not lose the input array! The best, most expensive is the disc brakes first!

Hand sent: If you want the brakes feel at ease, labor-saving light, brake power supple, only disc!

Downhill mad: Long sharp downhill, only disc in order to ensure consistent braking effect!

Attention topeak allay seat assembly

1. If the best size would be a good buy ALLAY cushion mounted directly in the original car, (car seat for the rod to remain in the original removed, then the seat height may increase the number. According to different models may be, please re-adjustments to a high degree of .

 

2. Generally speaking, need to be adjusted a little bit of forward ALLAY seat, your seat bones sitting on sit-zone on the right.

 

3. From the beginning may feel more insane that hard, it is because the original with the two ischial perineal cushion has supported a total of 3:00. ALLAY part because of the perineum no pressure, so only two ischial support the body weight, will feel more hard point, riding for a while to adjust to.

4.

 

4. To draw a larger car or uphill support, it can be hard to play a little balloon. General riding then release pressure valve when the pressure to let go will be more comfortable.

All the air bags are different sizes depending on the model are also different. Follow the correct type, size, choose to use.

 

5.ALLAY pressure-release effect of the world's best, the use of after, you almost can not let you use the general traditional perineal pain or intermediate tunneling, V-type cushion the gully.

To: "diaoogu.1108" <diaoogu.1108@blogger.com>

With the popularity of sports bikes, bicycle enthusiasts have more and more on par with professional athletes, have used self-locking pedal, perhaps since childhood and the domestic most people who grew up riding a bike, they will not feel self-locking necessary, but anyone who used self-locking would not change it back before the horizontal foot of the riding, which is the Why?

 

1. Self-locking in improving the speed climbing to help and protect the knee to correct the error position

 

2. Self-locking in the bumpy road that can help control the car, the foot will not slip, to improve safety

 

3. Self-locking good prolapse, even if the inevitable does not throw cars off can not afford to Lianren Dai car threw out, self-locking in the throw when undocked from the on his own. Skilled practice, and off the lock is not a problem.

 

4. Long-distance with the self-locking it easier and better to keep stepping frequency, and to reduce the possibility of thigh muscle pain.

 

5. Inexpensive self-locking and lock shoes are also a good choice, the less self-locking is not a distant thing.

 

6. Self-locking threw occurred mainly in the speed of 0 when the system forgot to unlock.

 

7. Self-locking technique is the growth of an XC only way that can make you a more professional, accustomed to self-locking is difficult to change overnight.

The difference between disc and V brake

First, a view is patted death is better than V brake disc brake, high-grade - seems strange new bicycle for movement of
Hand brake disc tend to think is better than V brake, we heard so: "are more than 2,000 car, there is no disk
Brake "- - that really make people laugh and cry, see whether abroad or domestic professional game,
If it is sunny, V account for the majority of the brake disc, of course, have also increased, but the brakes on
In most leisure riding and does not participate in the competition of the 1st amateur level, V V brake brake especially better or sufficient
Of course, like to ride downhill, like severe, like pendulum cool juyou disc brake or proper choice, but one
You, the disc brake or V brake of itself or Suggestions from using our customers from the Angle of his budget
Choose more reasonable.

1 first from design to see

Disc brake is through the clamping device (or called calipers) in HuaGu fixed in the steel plate braking, V brake is
After V brake clamps device to cling to circle the braking, relatively speaking, than the disc brake circle radius is too big, radius of CD dish so
Brake braking arm much smaller, thus theoretically more not easy to hold death, death to exercise bike brake requirements
It is the most basic, but not to lock the good play, unless such demand climbing skills. Hold die immediately
Sexual cycling.

1.1 weight

Must notice is generally lower than V brake disc brake 800g weight 1kg to car, high-grade car gap
To small. Separately, can see the weight to ride or influential factor, have to consider.


2 on the job characteristics

V brake friction is the mixture of rubber wheel rims and contact friction (generally, aluminum alloy car sales process, cheap is cast
The boundary, the so-called car edge and cast, car edge better), general braking effect is very strong, unless in the hold
High-speed downhill, continuous renewal, such as our next to brake yellow horse crossway when you touch a circle, also very
Hot, so the temperature of the brake force will be weakened. The higher the temperature, and also the effect of brake down badly.


Disc brake is a metal plate (usually of steel, high-grade aluminium alloy system also has the brake disc) and friction friction between rocks
To apply the brake, so the brake is very strong, and auto and motorcycle similar characteristics, is not subject to rain and poor road
The weather condition, because the disc brake friction blocks, such a metal sintering and pieces of steel friction, even if rain, and have
Under the condition of mud, work still good, braking force down although obviously superior to V brake, but the rubber and aluminum alloy
Gold circle friction. And because the disc brake disks are steel, but generally with holes in continuous process of brake downhill
Along with the increase of heat than V brake to decay.

From the price, the so-called ratio

If it is 1000 multivariate car and 2000 multivariate car, the proposal USES V brake, almost all the experience people are of the view
The disc brake, "low price as the medium, to use" V brake to explain this sentence, the disc brake low-grade price in 2
In multivariate to 300 yuan, including some Taiwan brand such as assess and yue, etc, including promax shim
The 475,495 ano official price in the disc brake, 500 multivariate these disc brake effect is very general, including the shimano
Quantity, but feels very hard. If the customer want to install dish commonly, although these disc brake mountain feelings for vehicle has
Goods, but usually we recommend, unless it is cool kid must be placed only so much money and will put cool, nor
Must not sell the few customers, new loading, V brake shimano except for the brand outside can choose, so very much
Easy to achieve the effect of brake middle-grade ear not much money, such as very classic Avid FR5 double-sided anaglyph shift +
Shimano M430 braking clamps, such a chariot of the price of $247 brake handle, but nevertheless than
Above the disk brake is much too much, if more budget, the same, but fr5 avid shift
Cooperate with the avid sd7 grade v brake (paperback version of the patch brake in 300 yuan, the hardcover 380 yuan, it is sex
Can very good V), so the brake brake system cost price but 400 yuan, but already belongs to high-grade brake
System upgrade and, of course, also can choose the shimano shift plus avid old style of V brake with Lx level
And, of course, use shimano high-grade V brake official expensive, so the LX is old, and there is worthwhile
Braking force is larger, the collocation is very good. With the price in the disk brake: such as our common shiman
O, 29, EF35 EF EF50 series with the handbrake wasn broadcast if shimano 475 disc brake -- - this money
680 yuan, the price is in mountainous feelings for garage sale 540 yuan (former) is still loading, feel very hard
A trip down the mountain to become daily vehicle, hand in the maintenance of many such collocation, meet customer
This is our price, upgrade tend to pain.

If is 2000 and 3000 multivariate car plates brake to calm some HuaGu brake disc (well, but it is very important also
Walk to the system problem, we recommend the disc brake the introductory level is also called for good disk brake ratio ha
Yes, the 2004one black version of the mx2 hayes, Avid, price in BB5 52 yuan, the price is in
62 yuan, this two special brake disc company do product is rigorous, feel acceptable, of course, such as Avid


7 disk brake handle the BB is sent a DaJie son, but quality is stable, feel badly control or clear disk brake
Sleep, plus the disc brake HuaGu slightly better, more ideal 3k price in the course of the disc, more high-grade brake
Again, such as the price of the avid up BB7 line deore shimano dish, the oil, the 525 dish is good
Choose.


4 the choose and buy new phase from actual brake system and upgrading the said

For young people, must ride in the mountains, and in the mountain of budget, can choose the disc brake, if the budget
In, or 1k 2k to benefit all, brake V total budget where, to rob Peter to pay Paul, right? If a
Begin to feel with disc brake after the HuaGu choose to upgrade trouble, or later!

For girls and elderly people, and leisure bike brake V more appropriate, light weight, easy maintenance.

To upgrade to the car from the configuration and the price on the overall consideration, many people said to change some money, and upgrade the braking system
Series, "give me the change to disc brake!" - then found HuaGu, frame, fork, etc will change, alas - price too
Big; secondly, the more money, or less 200,300 yuan, the change of middle-grade V, very good.
