The Hope Tech 4 EVO GR4 hydraulic disc brake is a gravity-specific system, providing robust power and heat management for demanding conditions. It suits bigger riders, downhill racing, and e-bike use. Key enhancements include a re-engineered master cylinder cam for a firmer bite and a new bleed port for simplified maintenance.

At the caliper, enlarged pistons deliver approximately 6% more stopping power compared to the previous V4 model. The brake system offers broad compatibility with various disc options, shifter and dropper matchmakers, and mounts for all rotor sizes, ensuring integration with diverse setups.
