Shimano Dura Ace BR-R9170 Rear Flat-Mount Disc Brake Caliper
Why Spec the Shimano Dura-Ace BR-R9170 Rear Disc Caliper?
The BR-R9170 is Shimano's Dura-Ace hydraulic disc brake caliper in flat-mount configuration, engineered for road racing where brake feel, modulation, and low weight are non-negotiable. The one-piece alloy body eliminates the flex points inherent in two-piece caliper designs, resulting in more direct lever feel and more precise control over braking force on high-speed descents and technical corners. Integrated heat dissipation fins in the caliper body pull thermal energy away from the pads and fluid during sustained braking, maintaining consistent hydraulic pressure and preventing brake fade when the rear brake is working hardest.
Tool access is designed for quick pad changes and wheel removal without caliper removal, keeping race-day service straightforward. The flat-mount interface is the current road disc standard, compatible with direct mount on all road and gravel frames specced for flat-mount calipers. The BR-R9170 runs on Shimano mineral oil, works with all Dura-Ace R9170 and R9100 Di2 brake lever pairings, and accepts finned resin or sintered pad compounds for tuning brake character to the conditions. This is the rear caliper for riders who want the full Dura-Ace disc experience.
