How to adjust the transmission of a bicycle and how to adjust the transmission of a bicycle

Should the front transmission of the bicycle move the chain up and down parallel to the chain? Yes.

Under normal circumstances, it should be parallel, but it is not ruled out that the front transmission and the chainring do not work well together, and a slight change of angle can make the transmission smooth.

Generally speaking, if the front derailleur can be compatible with large cranks, some mountain cranksets such as the maximum 48 teeth, and some front derailleurs are compatible within 44 teeth, which is a bit problematic to match.

How so? It's better to say anything than to see it yourself.,There's a post in the equipment experience section of the bicycle travel network that can**a dial**,You look for it yourself.,It should be searchable.,I'll get one.,It's very specific.。

Because there are 3 front cranksets and at least 6 flywheels, it is not possible to be perfectly parallel.

When riding a bicycle to climb a hill, you can adjust the front gear to 1, which is the largest gear, and the rear gear can be adjusted to 1-3, and the rear gear is the largest when adjusted to 1, so it is very easy on the uphill section. If the front gear is adjusted to 3, then the rear gear can be adjusted to 4. This can also be done in the event of a headwind.

Precautions for cycling:

Riding gear to wear:

Wear the necessary equipment before cycling, such as helmets, knee pads, wrist pads, etc., to protect your body from accidental falls, so remember to wear gear.

Check the condition of your car in detail

Before cycling, carefully check the various parts of your bike, such as brakes, tire pressure, transmission, etc., to ensure safe riding, and at the same time, it can also prevent us from being helpless on the road.

Always be aware of the vehicles around you:

Many tragedies are caused by carelessness, when turning a corner or when there are vehicles passing by, you must pay attention to the surrounding vehicles, and slow down, do not engage in dangerous movements, in order to prevent traffic accidents.

The transmission bike transmission can be adjusted using the following methods.

1. When the vehicle is going uphill, first adjust the left side to 1st gear.

2. Adjust to 1st gear on the right. If you find it strained, you can continue to adjust it up to 2nd or 3rd gear.

3. On the flat road, the left side can be adjusted to 5, 6, and 7 gears.

4. When going downhill, there are three gears on the left, and 5, 6, and 7 gears on the right can be used.

Answer: The transmission should be toggled while riding, and the chain must be pedaled slowly when dialing from the pinion to the big gear, and then speed up the ride after the chain is fully on the big gear, and vice versa. In addition, the gear on the pedal has the opposite effect of the gear on the rear wheel, so if you want to ride more briskly, you can also use the front gear smaller or the rear gear larger.

If you want to speed up your ride, do the opposite. The main function of the shifting is reflected in the climbing, if you are on flat ground or downwind, use a heavier riding style (big in the front and small in the back), if you want to climb the hill, choose a light riding style (small in the front and large in the back), as long as you feel no problem.

2. Shift speed before going uphill: When riding a mountain bike and need to change speed when encountering uphill, you must have good foresight, don't wait until you ride on the slope and then change speed (deceleration), you must change speed before going uphill, so that you need to ensure the speed and stepping speed when going uphill, and it is not easy to damage your knees.

3. Flat road shifting: remember to tread evenly when shifting, don't change gears (accelerate) when accelerating sharply, sometimes the transmission can not be very smooth when shifting, then you can push the gear lever a little past until the gear is in place.

1- 1 2 3 2- 3 4 5 63- 5 6 7 8 When starting, it is generally 2-4 to start Cruising at 3-5 normal speed Climbing is 1-123 according to the slope.

There are two that are disabled, one is the largest crankset with the largest flywheel, so that the tension of the chain is too great, and it is easy to damage the chain; The second is the smallest crankset with the smallest flywheel, which makes it easy to grind the front derailleur. The gear ratios of these two combinations can be achieved with the 3rd and 6th flywheels in the middle disc. The crankset usually uses the middle plate, and the collocation of the average person's foot force 26 is more appropriate, and 25 or 24 is used when encountering uphill.

If you want to increase your speed, increase the frequency of pedaling, so you'll find that you can ride longer without getting very tired. In order to protect the transmission system, try to use the following crankset flywheel ratio to ride, 3-5678, 2-3456, 1-1234, because the crankset and flywheel are not in the same plane, the chain will have a certain inclination, with 1-7 or 3-3 such a ratio, the inclination of the chain will be too large, and it is easy to be damaged after a long time. If the gear is very unsuitable for the road surface at that time, lift the rear wheel, idle the crankset to change the speed, and try not to move the dial when stationary, so as not to damage the dial.

It is normal for the chain to have a ring, indicating that your car is good, because the chain is usually oblique, and the transmission is used to adjust the speed, the front gear, the back is best to be a partner, the front 2 and the rear on, the front 3 and the rear. Depending on how fast your car is, the higher the grade, the harder it is to ride, so slowly change from low to high.

After reading your problem, the front derailleur must be caused by a loose shift line; As for the rear derailleur you are talking about, do you define it according to the flywheel from small to large or according to the gear marked by the right finger dial?

I'm a cyclist and I've been told that the gap between the left and right should not be too big, for example, the left is 3, the right is not 1, the left is 1, the right is not 7, if it rings, it is estimated that it is the friction of the dialer, go to the garage to adjust it, do not need money, about the labor-saving is that when the riding speed is fast, it is replaced by a big 3 and 7 Uphill, of course, it is a slow ride, and it is enough to change to 2 and 3.

3-7 Who told you this? 21-speed cars are usually 2-5 or 2-6 on the line, but the noise is because the speed change is not allowed to go to the car shop to adjust it for free.

1.The chain will rattle when changing gears, which is normal. 2 There is no need to adjust the speed change on the flat road, the chain is on the big tooth, the speed change is used when going uphill, the higher the gear hanging, the faster the speed, the more labor-saving! 3 If the noise is loud and the new car should put some oil on the chain, and idle it at the same time!

The position of the front derailleur is a bit off, and the Phillips change cone There are two screws on the front derailleur to adjust the position.

The dial (i.e., the handlebar-mounted transmission) can be adjusted, tightened, or loosened by rotating the shift cord.

There are two screws on the front and rear derailleurs, marked with "H" and "L" respectively, which can provide fine adjustment of the transmission, tighten the H transmission to the right, tighten the L transmission to the left, and can be adjusted when the chain is grinding or the upper gear is not smooth.

The transmission is not complicated, but the adjustment requires a certain amount of experience and skills, it is recommended that you go to the car shop to adjust it first, by the way, you can learn it quickly, but if you want to adjust it well, you need to practice often.

Happy riding!

First of all, you have to understand the relationship between the gear ratio in mechanical common sense, for example, the ratio of the front and rear gears (that is, the ratio of the number of rulers) is relatively small, such as 1:1, you pedal a circle in front of you, and the wheel behind you will also turn a circle (so it is simpler and there is actually a difference) It is easier to pedal. The front ** remains unchanged, and the back is put into the smallest wheel, and the ruler ratio is relatively large, such as 1:

4. You kick around in front of you and turn four times in the back. So it naturally takes some effort to stare at it. So if it's a gearbox, start with a smaller gear, as you said, it's easy to pedal, but when you ride fast, it's like dropping a chain, and then you can pedal faster and faster when you gradually switch to a gear with a larger footage, or in other words, you can change the speed with the same pedaling frequency.

This is the basic technique that cycling needs to master.

The transmission tube on the right is behind and the transmission tube on the left is in front, so it's three in the front and seven in the rear. There are two buttons on each transmission, the right one on the transmission is downshifted with a press of the thumb, the index finger is hooked to increase the gear, and the left one is the opposite. You shake your pedals and change the speed at the same time, and you can understand it after a few more practices.

As for the sound of the chain, it was because it was not adjusted at the time, and it was probably made when the smallest flywheel (the largest gear) was used in the back. It can be solved like this: the left derailleur has a knob, and you can turn it counterclockwise a few times.

If it doesn't work, you can only go to the car shop and ask the master to help you adjust.

The rear wheel you mentioned is the chain puller, and some of the front ones will have the same one. First of all, we need to know that we change gears in order to get the fastest speed with the least effort. The larger the rear sprocket, the easier it is to ride, and the slower it will be; Conversely, the smaller the rear sprocket, the harder it is to ride and the faster it will be.

We generally choose a lower gear with a rear sprocket when going downhill and a larger gear with a rear sprocket when going uphill.

If your bicycle front sprocket also has a chain puller, then the larger the front sprocket, the more strenuous and faster it will be; The smaller the front sprocket, the less effort it will have and the slower it will be. When adjusting, you should adjust it slowly, one gear at a time, so that the force will be more even. Also try to keep the chain in a straight line.

Step 1: Make sure that each cable is in the correct position, that it is stuck into the bayonet of the frame, and that the transmission cable is installed correctly. Then tighten the variable speed adjustment screw and loosen it back 3 turns, and the adjustment screw on the shift lever is similarly adjusted.

Straighten the wire as straight as possible and tighten the brake cable fixing screws on the rear transmission.

Step 2: Shift the lever to the middle setting, such as 4th gear. Then adjust the variable speed adjustment screw on the rear derailleur. When the chain is on the corresponding tooth, the guide wheel and the tooth are on the same plane.

Step 3: Adjust the limit screw: The function of the limit screw is to prevent the chain from falling out of the smallest piece of gear or getting caught between the flywheel and the wire.

You can adjust the minimum piece gear first. Release the shift wrench to its lowest setting. See if the smallest gear and guide wheel are in the same plane. Otherwise adjust the screws. Usually marked with H. Adjust to the same plane.

Then adjust the big gear side. The difference is to loosen the screw on the L side first, and then tighten it to the same plane of the two gears after the chain is hung up. That's basically the way to adjust.

The next thing is to give it a try. Let's try to change the speed of space. Normal should be supple and not beating.

If the upward speed change can not be in place in time, it means that the line is not pulled enough, you need to turn the adjusting screw out a little counterclockwise, usually half a circle and half a circle of adjustment is enough. If you can't change gears, loosen it a little. Then take a ride and see.

Usually, the new shift line needs to be adjusted slightly after a period of shifting.

Transmission adjustment steps for mountain bikes:There are 3 6, 3 7, 3 8, 3 9 and other types of mountain bike transmissions, if your car needs are just commuting in the morning and evening, buy 7 is enough, if you are mainly used for long-distance riding or professional racing, 3 8, 3 9 or even up.

If the front crankset is 1st gear, the rear flywheel is best used with 12345 gear, if the front is 2nd gear, the rear is best used with 234567 gear, if the front is 3rd gear, the rear wheel and bench surface are best used with 789 gear.

Chain, try to keep parallel to the body, even if not parallel, the angle of the cross is as small as possible, otherwise it will accelerate the wear of the chain, and even slippery silk, slippery silk car can not ride, you must use your hand to break the chain hard to the gear to get stuck, in order to continue to ride, the chain is very dirty, very troublesome, and not easy to break, so that the travel to, to observe the chain angle at any time.

The following methods can be usedRegulationVariable speed bikesTransmission.

1. When the vehicle is going uphill, first adjust the left side to 1st gear.

2. Adjust to 1st gear on the right. If you find it strained, you can continue to adjust it up to 2nd or 3rd gear.

3. On the flat road, the left side can be adjusted to 5, 6, and 7 gears.

4. When going downhill, there are three gears on the left, and 5, 6, and 7 gears on the right can be raised.

The role of the transmission.

The bicycle's transmission has a combined speed of 27 for the front 3 cranksets and 9 rear cranks. Take a mountain bike here.

This is illustrated as an example. When the pedal is rotated, the front tooth disc rotates, and the power is transferred to the rear tooth sedan through the chain, and the wheel moves forward. The size of the front chainring (number of teeth) and the size of the rear chainring (number of teeth) determine the force with which the pedals are rotated.

The larger the front chainring, the smaller the rear chainring, and it is laborious to pedal (the distance the bike travels longer). The smaller the front chainring, the larger the rear chainring, and the easier it is when pedaling (the distance the bike travels shorter).

The riding of a bicycle is to start, stop, go uphill, downhill, windward, downwind, etc. To be able to maintain a certain speed under any condition (whether the bicycle is moving fast or slowly, it can maintain a certain pedaling pace and torque, and the transmission is required.

Summary. Dear, I'm glad to answer for you: How to adjust the transmission of a transmission bike:

1.You can make the rear sprocket larger, and the smaller the effort, the lower the speed; On the contrary, make the rear sprocket smaller, and the more force you use, the faster it will be. 2.

When the bicycle is driving on a flat road, in order to speed up the vehicle, it is advisable to use a combination of a larger chain disc and a smaller flywheel; When the bicycle goes uphill, it is advisable to use a combination of a smaller chain disc and a larger flywheel, which is more labor-saving and easy to climb. 3.When starting, it is generally 2-4 to start, cruising and climbing at 3-5 normal speed is 1-123, and it is selected according to the slope.

Dear, I'm glad to talk about the answer for you: the method of transmission adjustment of the transmission of the gearbox: group lift 1

You can make the rear sprocket larger, and the smaller the effort, the lower the speed; On the contrary, the lower the rear chain collapse loss blue wheel, the greater the force, the speed will be very fast. 2.When the bicycle is driving on a flat road, in order to speed up the vehicle, it is advisable to use a combination of a larger chain disc and a smaller flywheel; When the bicycle goes uphill, it is advisable to use a combination of a smaller chain disc and a larger flywheel, which is more labor-saving and easy to climb.

3.When starting, it is generally 2-4 to start, cruising and climbing at 3-5 normal speed is 1-123, and it is selected according to the slope.

Kiss and expand: A transmission is installed on the handlebar of the front of the variable speed bike, so that the rider can adjust and control the speed of the bike. The left and right transmissions control the size adjustment of the front and rear gears respectively, and the gear can be changed by manual adjustment.

Before shifting, the chain of the bicycle is engaged with the front and rear gears; After adjusting the transmission, the chain and the original gear are changed from a meshing state to a separate state, and then meshed with another pair of gears of different diameters. With the same pedal frequency, the speed of the car changed.
