Shimano ST-R9120 + BR-R170 Dura Ace Disc Brake Set



Product Details

A completely new level of reliability and braking performance is achieved with Dura Ace disc brakes. Even under challenging weather conditions, the rider can set maximum trust in braking performance. Thanks to the flat mount construction, the BR-R9170 hydraulic disc brake caliper is mounted direct to the frame, giving it a flat profile and higher efficiency. The heat dissipation is greatly improved and this gives the rider stable braking performance throughout the entire ride.
