Technology

Servo Wave
When you operate a Servo Wave brake lever the first part of the stroke of the pad is very fast, so that small and precise movements of the lever allow contact with the disc. The power factor multiplies with increasing pressure on the lever, so that every braking is precise and fast, for greater control while driving.

The kit includes mechanical control levers, brake calipers with hoses, pads, hydraulic connectors and mineral oil.
Discs not included.
