In 2016, TRP began working with reigning world cup champion, Aaron Gwin, to redesign our DH-R EVO brakes. Out of the gate, he was impressed with the initial level of performance, but he did have a list of improvements needed to achieve world cup-winning performance.
Working closely with the TRP development team, improvements were made in nearly every part of the brake and tested on the world cup circuit throughout the season.
We took most of the changes made to the DH-R EVO brakes and put them into the Slate T4. This brake features the same ergonomic lever made from cast aluminum and a forged/CNC'd caliper, both of which were given a matte black finish. It also features a new and stiffer 5.0mm hose for easier internal routing and better transfer of hydraulic power. Riders will also find benefits in the four-piston caliper, tool-free reach adjust, and top-loading caliper.
