The TRP Slate T4 is a gravity-focused hydraulic disc brake developed in collaboration with Aaron Gwin, featuring a revised lever design for improved ergonomics and feel. This is the current 5mm hose production version, updated with the revised Gwin lever and new resin pads for strong initial bite and quiet operation.

  • Revised Gwin lever — ergonomically refined for better control and reach adjustment
  • 5mm hose — current production specification
  • New resin pads — strong bite with quieter operation than metallic pads
  • Post mount caliper — compatible with standard trail and enduro forks
  • Front brake unit (right lever — Australian convention)
  • Rotor not included

The TRP Slate T4 uses a mineral oil hydraulic system with a 4-piston caliper, tuned for the demands of gravity riding. The lever geometry refinements developed with Aaron Gwin focus on consistent feel across varying grip positions and braking intensities — critical for front-end control on steep descents.

Post mount caliper. Rotor not included. This is the front-only unit. See the companion rear SKU for the complete set.
