Product Review

After extensive testing, TRP brings an updated cable-actuated hydraulic braking system back to the cycling market with the HY/RD Cable-Actuated Hydraulic Disc Brake, offering you a cost effective way to achieve better braking power and modulation. First, you don't need to spring for new shift levers (which is the case with many fully-hydraulic designs), because the HY/RD is compatible with all existing cable-actuated systems. The hydraulic mechanism is located at the caliper to keep your bars tidy. Also, braking is always consistent with HY/RD's automatic pad wear adjustment, and with pads that are compatible with Shimano M525/M515 brakes, you have no trouble finding replacements. The calipers weigh less than 200 grams and are post mount with IS hardware included.
