EVO GR4 Brake
The Hope EVO GR4 Brake is a four-piston gravity brake built for descents and demanding terrain. Its lever features a roller bearing main pivot for smooth, consistent action, while two internal guide bushes keep each piston running straight. A bleed port on the master cylinder body simplifies maintenance, letting riders bleed the system without removing the reservoir lid.
The caliper uses a one-piece design that increases stiffness without adding bulk, and a new bore cap reduces overall width for better frame clearance. Caliper adjustment range is wider, suiting various hub and frame combinations, though vented rotors are not compatible. The system runs on DOT 5.1 fluid and includes a 2000mm hose with adjustable lever reach.
