Technology:


Gear Change Support
The Shimano shift servo uses pedal force to shift down. Therefore you can shift down quickly and precisely with little effort. The shift servo is of decisive importance for the automatic shifting system. This reduces the required shifting forces to such an extent that a small DC motor with low torque can affect the shifting operation. Power consumption is reduced and the system is lighter and more compact.
