Shimano Dura Ace ST-R9120 + BR-R9170 11S hydraulic control levers

A completely new level of reliability and braking performance is achieved with the Dura Ace disc brake system. Even under challenging weather conditions, the rider can set maximum trust in braking performance. Despite the integration of a hydraulic system, Shimano’s developers were able to keep the STI lever design slim and compact. Of course, the reach is adjustable so that the position of the levers can be individually set to suit the rider. The shift paddles now feature a more defined movement and have been extended in length for more confident and comfortable shifting.

Technology

Servo Wave
When you pull a servo wave 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.

Kit includes mechanic control levers, brake calipers with hoses, pads, hydraulic connectors and mineral oil.
Rotors not included.
