Quickshifter for Rapid Bike Racing control units, complete with sensor and specific wiring to match the control units.
The new electronics is able to communicate, via the CAN-bus line, with the Racing control units in order to carry out the self-calibration of the intervention times according to the force exerted on the sensor.
The cut-off times can be modified in the control unit, based on the number of revolutions and the gear position.
Note: the kit only works to engage the upper gear.
