The TRP HY/RD in High Polish Gun Metal Grey is the go-to cable-actuated hydraulic disc caliper for gravel and cyclocross riders who want hydraulic braking power without hydraulic brake lines. A standard brake cable actuates a self-contained hydraulic system inside the caliper — meaning you get consistent, powerful modulation with the simplicity of a mechanical setup.

  • Self-contained hydraulic system for smooth, consistent modulation
  • Compatible with standard brake levers and cable housing
  • High polish gun metal grey finish
  • Popular choice for gravel, cyclocross, and adventure road builds
