High-performance BR-RS785 hydraulic disc brake caliper designed for mountain and road bike applications for precise stopping power and control. Constructed with durable, lightweight aluminum alloy components that ensure reliable performance and ease of maintenance during demanding rides. Features resin brake pads with integrated cooling fins for enhanced heat dissipation, reducing brake fade and maintaining consistent braking performance in extended descents. Post-mount design allows versatile installation on a wide range of disc brake setups, suitable for both front and rear applications, with compatibility for standard bike frames. Engineered with hydraulic fluid system using mineral oil for smooth modulation, offering powerful, predictable braking under various riding conditions. Rim brakes are great, but they have an unfortunate penchant for not working well when wet or when a squirrel runs right out in front of you, so we look to the Shimano RS785 Hydraulic Disc Brake Caliper for reliable, all-condition, fade-free stopping power. It teams up with Shimano's ST-RS685 11-speed components for added performance and features IceTech cooling fins designed to dissipate heat, increase braking response, and keep performance high even during long, steep descents.
