With disc bikes gaining traction and winning plaudits for their four-season performance, the Shimano Ultegra R8070 Rear Flat Mount Caliper is a strong, double-sided disc brake caliper that's ready to take your braking reliability to the next level.

Recommended for use with a 140mm disc rotor, this hydraulic disc brake uses mineral oil brake fluid and mounts quickly and without a shim.

Shimano Ultegra R8070 Rear Flat Mount Caliper

Part of Shimano's Ultegra R8000 range, the Shimano Ultegra R8070 Rear Flat Mount Brake Caliper is a dedicated disc brake caliper that offers some of the most advanced performance credentials in the field to date. Mounting simply and without hassle onto your disc ready bike, this caliper takes 140mm disc rotors as standard and integrates seamlessly with the profile of your ride whilst improving your braking performance in all conditions.

Benefitting from a dual ceramic piston design, this flat-mount caliper grips your rotor disc neatly, providing even pressure to your rotor in order to give you that direct and immediate stopping force. Ceramic is used for enhanced heat insulation, levels of fade are reduced, and you can be sure of a longer lifespan in your brake set. An increased pad to rotor clearance engineered into this model greatly reduces the potential for rotor drag, allowing your wheel to move keenly and cleanly through the bike as you move at pace.

With a forged caliper design remaining lightweight and rigid, this rear flat mounting disc brake unit uses a one-way internal fluid circuit, making bleeding easy for any rider looking to do their own maintenance on their bike. Making use of non-corrosive mineral oil, this caliper boasts lower net temperatures and is recommended for use with Ice Tech FREEZA Centre-lock SM-RT800 rotors, providing a much better performing, longer lasting pad life with reduced temperatures.
