How to change speed on a mountain bike, 10 faster

My personal habits. You can refer to the following: Start before 2 and then 4 after the start, then change to the front 2 and 5 after a few quick kicks, the first 3 and the back 6 will basically slowly pedal, and then slowly rise according to your frequency.

This is different for each person, and the strength is different, and the method and time are also different. The point is that it's not like a car. Different gears for different road conditions.

The key is to find your most suitable cadence (a few laps in 1 second), higher than your most comfortable cadence will become high-end, low will be lower. The main thing is to find the speed at which you pedal and make yourself the most comfortable speed.

Do not spray personal experience masters.

If you are flat, use 2nd gear in the front and 5th or 6th gear in the back, and the frequency of foot pedaling should be fast.

When riding, it is to keep the frequency of pedaling, and then change the speed according to the road conditions, so that your frequency is as constant as possible, so that you can be relatively labor-saving, and the frequency of pedaling fast and slow will speed up the consumption of physical energy.

When changing speed on a flat road, you must keep pushing the pedal when you press the transmission with your hand. Also, if you want to change the speed when going uphill, although you have to keep pushing your foot, you can't push hard, otherwise you may break the gear. Leave it up to you.

It doesn't matter how fast or slow the speed is, take a look at the introduction below 1When changing gears (whether plus or minus), do not apply force to the pedal, and slowly rotate with inertia. Because the shifting system is fragile during the shifting process 2Try to avoid going uphill vigorously.

It's as simple as that.

Mountain bikesIt is safe to pass through any complex road surface, but the roads in the city are mostly flat, and the mountain bikes are not well played.

Tools Ingredients: Presentation Tools: Mountain Bike, Tool Type: 27-speed.

Reasonable use of fast mountain bikes: then carry the fiber in front of a gear and back in five, six, seven and eight gears; Hang two gears in front and two three, four, five, six, seven and eight in the back; Hang three gears in front and one, two, and three gears in the back.

2. When using, try to use as little as possible the largest gear with the largest flywheel, and the smallest crankset with the smallest flywheel. When using the largest chainring, the hidden flywheel is generally equipped with one, two, three, three, when using the mid-range, it can be used with two, three, four, five, and six, when using the smallest disc, it can be used with five, six, seven, eight.

3. The larger the front tooth disc, the smaller the rear tooth disc, and the more laborious it is when pedaling; The smaller the front chainring, the larger the rear chainring, and the more relaxed it is when pedaling.

4. Ordinary asphalt road: the left side of the front subdisc is fixed in the middle, and the rear tooth disc is operated by the right side of the direct dial; When going uphill: Use the smallest front chainring.

5. If there is an abnormal sound in the chain, see if there is too much stolen goods or lack of lubricating oil.

1. Adjust the left side to 1st gear when the vehicle is going uphill; 2. Adjust the right source side to 1st gear. If you feel that it is laborious, you can continue to adjust it upwards to 2nd or 3rd gear; 3. On the flat road, the left side can be adjusted to 5 gears, 6 gears, 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. Transmission as a more complex accessory on the bicycle, many people do not understand what parts of the transmission kit, how to use the transmission, how to adjust the transmission is inaccurate or stuck, read a circle, Sakura manuscript did not see a detailed article, here on my experience to talk about it, if you know the mistake of the song, welcome to correct, common progress!

Here's how:The first step, when the vehicle is going uphill, the transmission is adjusted to the first gear, and the first gear is specially used for climbing the hill, as shown in the figure below

The second step of the trouser sedan car, when it is on the flat ground, you can adjust it to 2 gears or 3 gears when you feel laborious to step on it, 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

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.

You set the front flywheel to 3 (the largest one) and the back flywheel to 7 (the smallest one) is your fastest speed of 21 speed (3*7=21), of course, you have to ride a little more than just now.

The front is generally in the middle, and the long flat road becomes bigger on the wheel. The back 7 is the smallest disc and the fastest downhill flat road. In turn, the larger the round, the more effort-saving. If you're still sinking in the front, middle and back 5 or 6, check to see if it's rubbing somewhere.

You're gearing 1-6 right now, and the chain is too off, and it might rub against the transmission, so it doesn't feel good to ride.

The first three and the last seven of the gear are the fastest and the most strenuous ones; The first one is the slowest and the last one is the most labor-saving.

Flat roads are generally used in 2-7 to 3-5 gears. Try it yourself more, and the party committee that suits you is the best.

The bigger the front and the smaller the back, the faster it is, and at the same time the harder it is to pedal, and the slower it is to turn around, but the uphill is easy.

Hummer bikes should be heavy and inherently resistant.

Be careful not to have the smallest front and the smallest back (or the front and the back), as this will wear out the chain.

According to different conditions such as flat land and uphill, there are different grade adjustment methods, as follows:

1. When the vehicle is going uphill, the Qiaofeng transmission is adjusted to the first gear, and the first gear is specially used for climbing, as shown in the figure below

2. When on the flat ground, you can adjust it to 2nd gear or 3rd gear when you feel laborious to step on it with 1st gear, 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, downhill time left Min Zhao side can be adjusted to 3 gear, as shown in the figure below
