How do you regulate mountain bikes? Come on

1. The fork lock switch can lock the fork so that the fork cannot be retracted. The fork hardness adjustment knob is to adjust the strength of the fork contraction.

2. This horn is usually called the deputy handlebar, the main role is to change the grip of both hands to reduce fatigue during long-distance riding, as for increasing speed, there is no effect, some people like to climb the hill like to grab the deputy handlebar, this depends on personal habits.

3. The locking fork is achieved by which fork locking switch is used. The suspension he said is the fork stiffness adjustment.

4. Compared with the V-brake commonly used in the past, the disc brake has good stability, good downhill safety for a long time, and is more reliable than the V-brake when encountering rain and mud, but the maintenance adjustment is more troublesome than the V-brake. Under normal use, disc brakes are not easily damaged.

5. The configuration of this car is completely at the leisure and entertainment level, and the forks, transmissions and disc brakes are relatively low-end products. This disc brake is not good, it is a decorative effect that is greater than the practical effect. The fork adjustment is very small and basically belongs to the decoration.

The transmission also only uses a finger dial and the front and rear dials are shimano, and the crankset flywheel is a miscellaneous brand.

At this price, it is recommended to buy Merida's Warrior 600 for an extra 300 yuan. Big brand, reliable quality, many people rely on this car to ride the Sichuan-Tibet line.

The fork can be locked, most of the locks are on the uphill slope, the soft and hard adjustment is based on personal conditions on the mountain road, it is the vice handlebar, and it is used to relax the wrist during long-distance riding, not to adjust the speed.

Locking and soft and hard adjustment is about the same, one is to rotate to one side, the other is to turn the lock, the advantage of disc brake is that the car effect is good in rainy days, but the maintenance is more complicated than ordinary line brakes, this ** configuration is OK, but it is still recommended to look at Giant or Merida if it is too expensive, Fujita is cheaper.

Finally, the bike is better to choose a 9-fly one, and an 8-speed one is a bit nondescript.

Summary. 1. You can lower the original stem by changing the relationship between the stem and the washer; You can also change the reverse front orientation of the stem or change it to a negative angle stem to reduce drag.

1. You can lower the original jujube stem by changing the relationship between the stem and the washer; You can also change the reverse front orientation of the stem or change it to a negative angle to reduce wind resistance.

2. The suspension fork of the mountain bike makes us more comfortable when riding on bumpy roads, absorbing and dissipating part of the shock, but we don't need to absorb the shock when riding on flat roads, so we can choose to lock the fork to reduce kinetic energy loss.

3. From the perspective of vehicle resistance, the impact of the tire may be the largest, the wide tooth off-road tire brings stable grip and will also produce huge friction resistance and weight, we can clearly hear the wind noise of the wide cherry blossom during riding, so if we do not go off-road for a long time, just commuting in a good urban environment or riding on the road for exercise, then the existence of off-road tires is particularly cumbersome and redundant.

In the case of shifting, the rear wheels are adjusted to the smallest gear. The pedal ** gear is adjusted to the gear of the largest disc. is the lightest!

What about shifting. What speed are you?

Xi Desheng's 21

If it's a 21-speed mountain bike. Well, its governor layout is pedal, and the cassette is 3-speed. The rear wheels are 7-speed.

If you want to turn your mountain bike to the lightest and fastest. Then they are not in the same gear as Qi. If you want to turn your mountain bike to the fastest speed.

Then the gear of the pedal flying like a wheel must be adjusted to the maximum canopy. The wheel gear at the rear wheel must be adjusted to a minimum.

The first three and the last one.

The rear wheels are tuned to the smallest gear. The pedal ** gear is adjusted to the gear of the largest disc. Generally, it is the first 3 and the last 7

When I first started buying it, he didn't oil the chain.

New cars do not need to be on the chain oil, generally 300-700 kilometers to do a routine maintenance, clean the chain, maintain the oil!

Remember to wipe off the water stains after the chain touches the water, otherwise it will oxidize and cause rust and the like.

Usually 200 kilometers with a clean cloth to wipe the chain.

Generally uphill or something, usually with a few speeds.

Uphill: If you want to move the bike forward to reduce your physical strength, adjust the left to 1, and the right 1, 2, and 3 are OK.

This one is universal!

Do you have any other questions, pro, the number should be over soon.

Will changing gears all the time affect the life of my mountain bike?

It won't reduce lifespan. Because different road sections need to be switched, Zhengkuan is similar to riding gears, and choosing the right speed is more labor-saving. If the speed does not change for the old, the governor is easy to be insensitive, and it may not be able to change back in serious cases.

Since the mountain bike is designed in this way, it is necessary to fully monitor its performance, how comfortable and how to ride, and do not worry too much.

The tuning tutorial is as follows:The first step, when the vehicle goes uphill, the transmission is adjusted to the first gear, and the first gear is specially used for climbing, as shown in the figure below

The second step, when on the flat ground, use 1 gear only to step on the number of holes and feel that it is laborious to adjust to 2 or 3 gears, as shown in the figure below

The third step, when you need to stand and ride, you can adjust to 5 gears, 6 gears, and 7 gears, as shown in the figure below

The fourth step, when going downhill, the left side can be adjusted to 3rd gear, as shown in the figure below

It is necessary to choose a reasonable gear ratio according to the road conditions and your physical strength, so that you can ride it both labor-saving and fast.

Here's how:

1. Ensure that the tires have the right pressure.

Maintaining the right tire pressure is an important part of increasing your riding speed. Every time you ride, you need to check to make sure you have enough dust pressure. Insufficient tire pressure means an increase in rolling resistance.

Not only is it laborious to ride, but the speed is greatly disturbed, and there is also a risk of a puncture anytime and anywhere.

2. The method of riding uphill and downhill, accelerate in advance before going uphill, rush the slope with speed, the speed will decrease after going uphill, and the gear should be retreated in advance, and the gear shift is not allowed when going uphill, and a little force and inertia can be used when going downhill.

A lot less force can be used on a horizontal road.

3. Reduce a lot of unnecessary braking. Brakes will slow you down. When you accelerate again, you need to put more and more effort into pedaling it. The number of brakes for the first time should not be too high. If you follow the expressway.

Or ride downhill to search for Zen, you don't notice should brake frequently. Always pay attention to your surroundings before braking. If the real-time traffic conditions are good, there are no obstacles, and there is a straight line ahead, then there is no reason to slow down.

The function of this bicycle shifting system is to match the transmission chain with different sizes of front and rear gear discs to change the speed of the car. The front gear is 1, the rear gear is 1234, the front gear is 2, the rear gear is 234567, the front gear is 3, and the rear gear is 789.

According to the visual road slope to determine, the first 2 rear 5 gears are generally used for acceleration, the larger the transmission value, the faster the speed, but the most strenuous when riding.

The size of the front chainring and the size of the rear chainring determine the strength of the bike when it rotates the pedals. Depending on the rider's ability, the speed of the bike can be adjusted by adjusting the size of the front and rear chainrings, or it can cope with different road sections and different road conditions.

Mountain bike transmission adjustments.

One. A few prerequisites.

1.Back dial. 1) Right finger dial **) to the maximum number, the chain is hung on the minimum gear of the flywheel group, the flywheel group is in the maximum transmission ratio, the highest speed, the minimum torque, and the rear dial is in the most relaxed state. On the contrary, the minimum gear ratio, the minimum speed, the maximum torque, and the tightest state at the rear derailleur.

2) Chain gear limit screw:

High (H) speed gear limit screw: control the position of the chain into the minimum gear of the flywheel group to prevent the chain from flying off; Twist out counterclockwise.

loose), the chain moves to the outside of the smallest tooth, and if it is too loose, the chain will fly off and get stuck between the flywheel group and the rear fork; On the contrary, if it is screwed in (tight), it moves to the inside of the smallest tooth, and if it is too tight, the chain cannot enter the position of the minimum tooth, or beats, or makes abnormal noise.

Low (L) speed gear limit screw: control the position of the chain entering the maximum gear of the flywheel group to prevent the chain from flying off; Rotate counterclockwise.

Out (loose), the chain moves to the inside of the largest gear of the flywheel group, and if it is too loose, the chain flies off and is stuck between the largest gear and the rear wheel spoke, which is dangerous; Screw in clockwise (tight), the chain moves to the outside of the largest tooth, too tight, the chain can not enter the maximum tooth, or beat, or abnormal sound.

3) Rear derailleur tension trimmer nut (loosen clockwise, tighten counterclockwise):

Quantity: 2, 1 each at the rear dial and 1 at the finger dial.

Function: Fine-tune the tension of the rear dial to control the chain to accurately enter the specified tooth.

Adjustment: Twist out counterclockwise (loose), increase tension, and use it for poor winding when changing speeds; On the contrary, screwing in (tight), the tension is relaxed, and the lower chain is not smooth when changing speeds. It is generally not recommended to adjust the finger dial.

4) Rear dial tension adjustment screw:

Function: Adjust the spacing between the guide wheel and the maximum tooth of the flywheel group, 6 mm.

Screwing increases, and vice versa, decreases.

2.Front derailleur: left finger dial **) minimum number, the chain is hung on the crankset minimum tooth, the crankset is in the minimum transmission ratio, the lowest speed, and the front derailleur is the most relaxed.

3.Two. Adjust the order:

1.Dial first and then dial, then dial forward.

2.After dialing, first adjust H, then adjust L.

3.Dial forward, first to L, then to H.

Three. Rear dial adjustment.

1.Disassemble (take off) the chain first, and maintain it by the way. Only in this way can the chain avoid the interference of the adjustment and make precise adjustments. If it is easy to adjust, you can go directly to the next step without disassembling (picking) the chain.

2.Loosen the rear derailleur fastening screws.

3.Adjust the H screws and move the rear dillerailleur laterally by hand so that the centerline of the guide wheel is aligned with the outside of the smallest tooth.

4.Adjust the L screw and move the rear derailleur laterally by hand so that the centerline of the guide wheel is aligned with the inside of the largest tooth.

5.Chain clearance adjustment: Put the chain in the front small and rear large position, adjust the rear dial tension adjustment (b) whole screw, so that the distance between the guide wheel and the maximum gear piece is 6 mm.

6.Put the finger dial **) in the highest speed position, at this time, the rear dial is the most relaxed, and then, turn the rear dial tension fine-tuning nut clockwise to the end, and then turn counterclockwise, reserve a margin for subsequent fine-tuning.

7.According to the front small and the back small, install the chain, at this time, the front and rear derailleurs should be in the corresponding position.

The smaller the rear wheel used, the faster the speed, and the larger the front wheel, the more laborious, according to their own physical strength and road conditions. For example, on flat ground, you can use small rear wheels and large front wheels, and when you are not strong on the uphill slope, you can use small front wheels and large rear wheels, although it is labor-saving, but the speed is slow.

The rear wheels mainly control the speed, and the smaller the gears used, the faster the speed, and there are several gears representing several gears. The gear of the rear wheel is generally on the right handle of the bicycle, and there are 7 gears, which correspond to different gears, and you can adjust the gear by yourself as long as you swing back and forth.

The front wheel mainly controls the force, and the larger the gear used, the more force is used when pedaling the bike, and there are several gears that represent several gears. The gear of the rear wheel is generally on the left handle of the bicycle, and there are three gears in the front, middle and rear, which correspond to different gears, and you can adjust the gear by yourself as long as you swing back and forth.

Riding a variable speed bicycle The correct posture of a mountain bike generally needs to grasp 2 points:

The height of the saddle, when the heel steps on the pedal to the bottom, the whole leg is just straight, adjust the angle of the saddle and the angle of the handlebar, so that the back is arched when riding, not straight.

A simple description of the transmission.

1. The gear lever on the right side of the grip (which may be engraved with a 1 9 word mark) is used for shifting the rear transmission.

2. The gear lever on the left side of the grip (which may be engraved with a 1 3 word mark) is used for shifting gears of the front transmission.

When shifting gears while riding, the transmission moves the chain to the chainring. When you stop to change gears, the chain won't move until you turn your feet.

Usual usage.

When riding on normal roads, the front chainring (operated by the gear lever on the left) is fixed in the middle (or maximum chainring 1). Using only the rear chainring (operated by the gear lever on the right) is easier to understand. The smallest front chainring is used when going uphill.

How to choose the gear ratio of the rear chainring? This is determined by the number of rotations of the pedal: the number of rotations of the front chainring (central axis) for 1 minute. So what is the best number of rotations?

It varies according to the strength of the feet, the technique, and the cardiopulmonary function. Generally 70 80rpm, 2 is more suitable.

1. When you want to speed up, start with a lower chainring (the larger chainring at the back), and change to a higher gear (small chainring at the back) as the speed increases.

2. The speed will be reduced when going uphill, and the gear ratio will be reduced to maintain a certain pedaling strength.

3. When downwind, the speed will be accelerated, and the gear ratio will be increased to maintain a certain pedaling strength.

The larger the transmission number, the faster the speed, and vice versa, the transmission on the handlebar generally, the left hand is the chain dial of the crankset (front gear), the right hand is the chain dial that controls the flywheel (rear gear), the left hand dials the number forward becomes larger, and the backward dial number becomes smaller, and the right hand is the opposite, some mountain bikes have the opposite of the transmission on both sides, pay attention to it, the gear shift is not to exert force, otherwise it will wear out the flywheel and crankset.
