Shimano Disc Brake Caliper Dura-Ace BR-R9170 Flat-Mount Rear

Hydraulic road disc brake caliper BR-R9170 for rear with Flat-Mount and L02A disc pads.

Two braking options now exist for riders at DURA-ACE 9100 level - mechanical rim brakes or hydraulic disc brakes. Hydraulic road disc brakes in the new DURA-ACE line-up add an extra element of control and confidence to brake performance in tough (weather) conditions. Hydraulic disc brake calipers can be directly mounted on the frame (flat mount) for a clean low profile design. New dedicated DURA-ACE rotors bring better heat management properties to provide stability in brake performance. With an increased adaptor size, heat transfer through the rotor is decreased and more heat can dissipate through the air. This results in a 30°c reduction in rotor temperature over Shimano’s ICE TECHNOLOGIES FREEZA rotors.
