After extensive testing, TRP brings an updated cable actuated hydraulic braking system back to the cycling market with the HYRD 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 HYRD 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 HYRD's automatic pad wear adjustment, and with pads that are compatible with Shimano M525M515 brakes, you have no trouble finding replacements. The calipers weigh less than 200 grams and are post mount with IS hardware included.
