The Shimano BR-R8070-F is a front-mounted hydraulic disc brake caliper from the Ultegra R8000 series. It features a compact, flat-mount design that fits neatly to road bike forks, maintaining aerodynamic lines and minimizing weight. This caliper uses mineral oil for consistent hydraulic braking and is compatible with a wide range of road bike frames with flat-mount standards. The BR-R8070-F is engineered for road cyclists who require reliable stopping power in all weather conditions, from dry tarmac to wet or muddy roads. It integrates ICE Technologies for heat dissipation, reducing brake fade during long descents and prolonging pad life. The caliper works best with the recommended SM-RT800 brake rotor and Shimano ST-R8070 or ST-R8020 levers.

For installation, the caliper’s low-profile and direct-mount design make for a clean and straightforward fit with road frames, and it includes options for various rotor sizes (typically 140/160mm with appropriate adapters). The use of aluminum for the housing and steel for caliper components offers a balance of lightness and durability. Maintenance is simplified with a one-way oil routing system that prevents air bubbles and makes bleeding and servicing straightforward.
