How is the speed of the mountain bike transmission adjusted?
The transmission of a mountain bike is divided into two parts. The left hand controls the front plate and the right hand controls the rear flywheel. It is usually adjusted in the way of “rear-based and front-assisted”; the gear ratio that is more difficult to pedal is also called heavy pedaling or high speed. The function of gear is labor-saving and time-saving, suitable for acceleration or downhill on flat roads; the light gear ratio, which is more labor-saving, is a powerful tool to overcome climbing.
The front derailleur adjusts the position of the mountain bike chain hanging on the chainring, which is adjusted with the left hand. The rear derailleur is a frequently used transmission. It adjusts the position of the road bike chain on the flywheel and adjusts it with the right hand.
