The TRP Hylex RS Flat Mount rear unit brings full hydraulic disc braking to drop bar road and cyclocross bikes with a flat mount caliper for clean integration on modern frames. This rear unit comes with a left-hand drop bar lever, 1800mm hose to accommodate longer rear routing, stainless hardware, and a mineral oil hydraulic circuit.

  • Flat mount caliper — modern road and gravel frame integration
  • Left-hand drop bar lever — rear brake setup (Australian convention)
  • 1800mm hose included — longer hose for rear frame routing
  • Stainless hardware — corrosion-resistant for all-weather riding
  • Mineral oil hydraulic system — consistent feel, easy to maintain

The Hylex RS uses mineral oil which is gentler on painted surfaces and easier to handle during bleeding than DOT fluid systems. The flat mount standard is now the norm on modern road and gravel bikes. The longer 1800mm hose on this rear unit accommodates most full-size road frame internal or external rear brake routing.

Flat mount rear caliper. 1800mm hose. Left-hand lever. Rotor not included. Compatible with flat mount road and gravel frames.
