How do I change gears on my mountain bike 18 speeds?

Uphill to 12th gear, better up, if it is a steep slope on the 10th gear, do not change gears when going uphill, it is best to get better before starting to go uphill, otherwise, the car with poor performance is easy to get stuck; Downhill with 18th gear, you can play the fastest speed of your car when going downhill; Start with 6th gear, and then gradually change to 18th gear. If you want to accelerate, use 12th gear first, and when the speed has started to come up a little, you will adjust it to 18th gear.

McLus has you covered:

1.In fact, to tell you a lot of truths, you can only be more confused after reading it, and you will understand it immediately after you actually ride at high speed a few times. You only need to know the front piece of the left hand tube (those pieces of the central axis), and the back piece of the right hand tube (those pieces of the rear axis).

This one is fixed. As for how to change, it is a large and small piece, because there are many kinds of transmission systems, and the direction is reversed and correct, and you will know when you get the car and try it yourself. After mastering the left hand, before and after the right hand, and how to change the size of the piece, you can look at the following.

2.The smaller the front teeth, the slower the speed, but at the same time the faster you start the car (because it's lighter).The lower the teeth, the faster, but at the same time the harder it is to get started.

3.Generally, the flat road uses the front middle tooth belt to start with a few teeth in the middle, and then the back slowly becomes smaller, and the speed is getting faster and faster.

4.But the more you change like this, the more you feel that you can't step on it. So what is the principle of shifting? The principle is to just use a little strength to step on it, and at the same time not to step empty. As soon as you get in the car, you can understand this as soon as the speed changes.

5.Generally speaking, the frequency of beginners pedaling is 60-80, and it will get faster and faster after training, but generally speaking, 80-130 is fine, too fast and the heart will not be able to stand it. Athletes will be faster.

6.Master the correct combination: the largest piece in front should not bring the largest 1-2 pieces in the back, the smallest piece in front should not bring the smallest 1-2 pieces in the back, and the middle piece with 3 pieces in front should try not to bring the largest and smallest 1 piece in the back.

It's not that this combination can't be used, but this combination is unscientific, and using such a combination for a long time also has a certain amount of damage to the car chain. It's okay to use it once in a while, especially when it's a game.

Don't think it's stupid to step on it quickly, that's the scientific method.

OK, what else don't you understand?

18-speed mountain bikes usually have a three-piece front crankset and a rear six-piece cassette to achieve shifting.

Shifting method for 18-speed mountain bikes:

1. The inside of the left hand brake handle is the gear shift handle that controls the front derailleur, also called the finger dial, push the finger chain forward to switch from the small crankset to the large crankset, and pull the finger chain backward to switch from the large crankset to the small crankset.

2. The inside of the right-hand brake handle is the shift handle that controls the rear derailleur, also called the finger dial, push the finger dial chain forward to switch from the small flywheel to the big flywheel, and pull the finger dial chain backward to switch from the big flywheel to the small flywheel.

1. The number of crankset pieces x the number of flywheel pieces Speed section (or section speed). 3x7＝21 3x8＝24 3x9＝27

The same goes for 3x10, 30 speeds, 2x11, 22 speeds, 1x12 12 speeds, 2x12 24 speeds, and so on. "21-speed" or "12-speed" with a hole in the hole indicate how many speed gears can be adjusted.

2. The decisive part of this is the flywheel. There are several pieces of the flywheel to represent the speed (speed level), for example, the above corresponds to the 7 speed, 8 speed, 9 speed, 10 speed, 11 speed, 12 speed. The higher the speed level, the more advanced the technology (because the more the flywheel develops, the narrower the piece, the chain also narrows, and the accuracy of the derailleur also increases).

At the same time, the higher the number of flywheels, the greater the climbing ability (because the increase is the largest inside piece). In principle, it is 12-speed (currently the mainstream) with climbing ability, 11-speed, 10-speed, 9-speed, and 8-speed. As a result, the 27-speed section has better technical and climbing power than the 21-speed stool section.

But if you're mainly riding flat roads and uphill bridges in the city, the 21-speed section is enough, and the 27-speed section isn't much better.

3. Also look at the brand. Even in the 8-speed class (3x8 24-speed section) released in 2007, the smoothness and tolerance of the Shimano shifting is better than that of the current miscellaneous brands. Shimano, Shimano, whatever the ride** or forum inquire, the two leading brands of shifting kits (the other pure one is SRAM, Speed Link).

If it's microshift, then it's okay, after all, it's in third place (despite the global share of 70% of Shimano and Superlink). I can't say whether the rest is good or not, but it just solves the problem of whether there is one.

The adjustment of the rear transmission of the mountain bike needs to rotate the governor, and the transmission wheel of the rear wheel will move the position, so that the chain change gear can achieve the purpose of changing the speed, and the specific operation steps are as follows:

1. Firmly support the mountain bike.

2. The rear wheel shift switch on the left side of the active handlebar.

3. At this time, the variable speed wheel of the rear wheel moves.

4. The initial position of the chain.

5. Position after moving.

Notes:1. The larger the rear wheel gear, the slower, but more labor-saving.

2. The smaller the rear wheel gear, the faster, but more laborious.

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

1. Change speed before going uphill, when riding a mountain bike when you need to change speed when you encounter an uphill slope, you must have a good foresight, don't wait until you ride on the slope and then change speed (decelerate), you must change speed before going uphill, so you need to ensure the speed and stepping speed when going uphill, and it is not easy to damage your knees.

2. Shift on a flat road, remember to keep the pace evenly when shifting, and don't change gears (accelerate) during rapid acceleration 3. Sometimes the transmission can't be geared up smoothly when shifting, so you can push the gear lever a little bit until the gear is in place.

4. Under special circumstances, if the gear cannot be in place when decelerating uphill, the step will be slowed down slightly, and the speed can generally be changed smoothly.

There is no trick, just don't press too hard when changing gears, otherwise it is easy to damage the flywheel. The point is that shifting is the most unstable period for a shifting package, just keep that in mind.

You can change it however you want.

Where is the skill, just don't step on it too hard when changing gears.

The first step, the vehicle uphill to the left side of the shift to a gear, the second step, when stepping on the feel that it is effortless, you can adjust to 2 gear or 3 gears, the third step, the flat road state, the left side of the degree can be adjusted to 5 gears, 6 gears, 7 gears can be adjusted to the fourth step, downhill when the left can be adjusted to 3 gears, you can also adjust according to your liking, in special cases, if you need to slow down downhill when you can't put the gear in place, you can slow down the step a little, and you can generally change the speed smoothly.

After watching it for a long time, I didn't understand how many front wheels are required for uphill climbing, and how many rear wheels are needed.
