TRP’s HY/RD gives you the performance and feel of hydraulic disc brakes with one simple—but significant—change to your existing mechanical disc-equipped road or ‘cross bike. The HY/RD (High Road) uses your current cable to activate the hydraulic caliper for more power and modulation than a conventional mechanical disc brake. The dual-piston caliper engages both brake pads when you squeeze the lever, so a crisp, responsive lever-feel accompanies your excellent stopping power. Available with 140mm or 160mm rotor options, these brakes deliver the perfect amount of control for your needs, whether it’s long, hilly descents or frequent, lower-speed dismounts in cyclocross. Plus, their slim profile tucks in neatly for great aerodynamics and minimal obstruction on chaotic ‘cross remounts, so the HY/RDs will only slow you down when you want them to.
