How to switch speeds on a bicycle?

You bought a multi-speed bicycle. But at once there was a question, how to switch speeds on a bicycle, and for what mechanisms of a choice of transfers are necessary? With the correct selection of the transmission, you can change the speed of the pedals and choose the force at which energy will be spent most efficiently and efficiently. When changing the gear ratio between the wheel and the pedals, the effort required to apply the cyclist to different parts of the road also changes. If you need to climb a steep mountain, the gear is selected lower, then the force applied to the pedal is reduced, although the number of turns of the pedal and increases. When descending from a steep mountain, on the contrary, the maximum transmission is established, and the speed can be developed very high. In order to make the change of speeds on the bike on the go, and there are speed switches.

There are several rules regarding how to switch speeds on a bicycle:

- switching speeds can be performed only when the bicycle is moving;

- for the safety of the switching mechanism, the load on the circuit must be minimal or absent altogether;

- it is impossible to increase the gear when climbing a mountain, it is better to try to establish the necessary gear before the lift;

- You can not switch gears abruptly from one to another, you need to do this smoothly, waiting until the previous transfer is fully established;

- the misalignment of the chain is not permissible.

How to switch the speed on a bicycle when climbing a mountain? It is necessary to set the necessary gear before lifting (as accurately as possible try to determine the length and steepness of the lift and switch in time).

Full adjustment of the speed on the bike is carried out at the retail outlet where you bought the bicycle. The buyer will only need to adjust the front or rear switches.

Consider how to switch the speed on the bike. The task of the front brake is to transfer the chain from one sprocket to another. In this case, by means of a parallelogram-shaped mechanism, the frame through which the chain passes is moved. If you need to switch the speed, the frame moves and takes a position above the desired star, the chain also jumps over it.

Switching the rear brake, as well as the front one, consists of tossing one bicycle chain from one star to another. The difference is that the front switch uses up to three stars, and the rear switch is set to nine. In addition, the rear derailleur provides tension to the chain. There is a special frame for this.

There are several general rules for setting speed switches on a bicycle. First of all, you can not use the switch of one bicycle to another. So, for mountain bikes, you can not use switches designed for highways. There is a limitation in the choice of the maximum diameter of the star in the switch. The ratio between the smallest and largest stars should be such that the switching is carried out correctly.

By following these simple rules, you will enjoy a comfortable ride on a multi-speed bike.
