BR-RS805 Brake Caliper

Product Information

The Shimano BR-RS805 Flat Mount Hydraulic Disc Brake Caliper offers a significant upgrade for road, cyclocross, and gravel bikes seeking reliable all-weather stopping power. Its road-specific Flat Mount design integrates cleanly into modern frames, providing a sleeker and often more aerodynamic profile than traditional post-mount calipers. This hydraulic system delivers consistent braking performance with excellent modulation, ensuring confident control whether you're descending steep grades or navigating technical terrain.

Engineered for straightforward maintenance, the BR-RS805 features a one-way bleeding system, making fluid changes and air removal simple. The caliper is constructed from lightweight aluminum and utilizes mineral oil for safe and efficient hydraulic operation. It comes equipped with L02A-R resin pads that include cooling fins, enhancing heat dissipation for sustained performance.
