Benefits & Features
Lever reach adjustment
Easy shifting and braking by the best lever position.

SERVOWAVE ACTION
When you pull a SERVOWAVE brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control.
