TRP DH-R EVO MTB Brake Line

TRP DH-R EVO MTB: a hydraulic brake line made for descending

4-piston caliper and 9mm lever piston: power under one finger

The 9mm lever piston raises the hydraulic ratio, turning lever travel into genuinely usable power with a single finger. Paired with the 4-piston caliper and its lightweight hybrid pistons, it helps reduce arm pump over long descents. The ergonomic lever blade, developed with Aaron Gwin, uses a dimpled surface that keeps your finger planted.

5mm hose and banjo connection: steady hydraulic pressure

The 5mm hydraulic hose is optimized for internal routing, with improved thermal stability and added rigidity that supports greater hydraulic pressure. The banjo connection makes it easy to angle the hose at the caliper for a clean build. Clearance is designed around 2.3mm thick rotors, which helps when heat builds up.

Who is it for?

This brake suits downhill, enduro and electric mountain bike riders who string together steep, technical sections. It has also earned multiple World Cup victories at the highest level of downhill racing. Compare it with our bike brakes to find the right match for your riding.
