The TRP HY-RD disc brake caliper uses an open hydraulic system that's compatible with cable-actuated Shimano and SRAM road shift levers. It features a master cylinder housed at the caliper end.
This top-quality model features a piston that's actuated by a cam and a roller system to eliminate any free play and initial friction. Additionally, its classic split clamp design makes the master cylinder easy to install on your handlebars without having to remove anything else. Finally, it's directly compatible with any Shimano I-Spec type shifter, so there's no need for an additional mount to attach the shifter to the master cylinder. Please Note: These brakes are sold individually and do not include rotors.
