The TRP Slate T4 is a gravity-focused hydraulic disc brake developed in collaboration with Aaron Gwin. This is the older 5.5mm hose version — earlier production specification — offered for riders requiring the original hose diameter for replacement or compatibility with existing setups.

  • 4-piston hydraulic caliper — gravity-grade stopping power
  • 5.5mm hose — older production version (note: current version uses 5mm hose)
  • Post mount caliper — compatible with standard trail and enduro forks
  • Front brake unit (right lever — Australian convention)
  • Rotor not included

The Slate T4 uses a mineral oil hydraulic circuit with a 4-piston caliper tuned for gravity disciplines. This older hose version uses a 5.5mm diameter hose — important to note when sourcing replacement hoses or fittings, as it differs from the current 5mm specification.

Post mount caliper. Rotor not included. Verify hose and fitting compatibility before ordering.
