you bought multi-bike.But immediately the question arose as to switch the speed of a bicycle, and what mechanisms need a choice of transfers?With proper selection of the transmission can be varied cadence and choose the force at which the energy will be spent more efficiently and effectively.If you change the gear ratio between the wheel and the pedals changes and effort you want to put the rider in different sections of the road.If you need to climb a steep hill, the transmission is selected lower, then the force applied to the pedal is reduced, while the number of revolutions of the pedals and increases.When descending a steep hill, on the contrary, it is set as high as possible transmission speed and can develop very high.In order to make shifting gears on a bicycle on the go, and there are switches speeds.
There are some rules on how to shift gears on the bike:
- gear change can be made only when the bicycle;
- for the safety of the switching mechanism of the load on the chain should be minimal or absent;
- impossible when climbing uphill to increase the transmission, it is better to try to set the right gear before lifting;
- can not dramatically shift gears from one to another, it should be done gradually, waiting for the previous transfer is fully established;
- distortions chains are not allowed.
How to shift gears on a bicycle when climbing a mountain?It is necessary to put the right gear before lifting (as closely as possible to try to determine the length and steepness of the rise and time switch).
Full speed setting on the bike is carried out in a shop where you bought the bike.Buyer will only need to adjust the switches front or rear.
Here's how to switch the speed of a bicycle.The task of the front brakes is the transfer of the chain from one sprocket to another.In this case, by a mechanism having the shape of a parallelogram frame is moved through which the chain.If you want to change the speed, the frame moves and takes a position on the right sprocket chain also jumps on it.
Changing the rear brake as the front, is throwing from one star to another bicycle chain.The difference is that the front derailleur is used to three stars, and in the rear is set to nine.In addition, the rear derailleur allows the chain tension.For this purpose there is a special frame.
There are some general rules for setting speed switch on the bike.First of all, one can not use a switch to another bicycle.For mountain bike you can not use switches for highways.There is a limit in selecting the maximum diameter of the star in the switch.The ratio between the lowest and highest star must be such that switching is performed correctly.
By following these simple rules, you'll enjoy a comfortable ride on the multi-speed bicycle.
