HY/RD Cable-Actuated Hydraulic Disc Brake

Cable actuated hydraulic disc brakes had a short burst of popularity during the late '90s because they were compatible with the existing mountain bike levers on the market. Given the combination of shifter and brake levers on our road bikes, Cable-Actuated Hydraulic Disc Brakes make the most economical sense to achieve better power and modulation. TRP's HY/RD has thoroughly tested to bring this technology up to speed and back to the cycling market.

The HY/RD is compatible with all existing cable-actuated systems, saving you major coin over fully-hydraulic designs that require new shift levers. It also reduces clutter at the bars by locating the hydraulic mechanism at the caliper. The HY/RD features automatic pad wear adjustment so braking is always consistent and it uses pads that are compatible with Shimano M525/M515 brakes, so replacements are always easy to find.

The HY/RD comes with semi-metallic pads that work well in dry conditions but may wear quickly in wet/muddy conditions. If you plan on CX riding an upgrade to full metallic is recommended, but they will be slightly louder. The calipers weigh under 200 grams and are available in Black anodized or polished finishes. You can chose 160mm or 140mm rotors, and the calipers are post mount, but IS hardware is included.
