Hope EVO GR4 Disc Brake Lever Set - Right Hand Post Mount 4-Piston Braided Hydraulic Hose

The Hope GR4 is a four-piston gravity brake designed for the most demanding applications, delivering maximum power without compromise. Super-smooth lever action and premium construction make controlling that power feel natural, establishing it as the benchmark brake for gravity and e-bike use. The increased lever hook provides greater control and security during aggressive riding, while a new dimple design improves comfort during hard braking and retains grip in all weather conditions. A new cam design decreases the free lever stroke while maintaining the feel and modulation in the braking zone. The brake features a roller bearing main pivot and two guide bushes to keep the piston running perfectly smooth and straight. The one-piece caliper design delivers the best stiffness to weight ratio, resulting in improved lever feel and increased power. Note that GR4s are not compatible with vented rotors. Larger pistons increase the brake ratio for more power, while a new bore cap design decreases overall caliper width for easier packaging and better frame compatibility. The brake offers a larger adjustment range for better compatibility with third-party hubs and frame combinations. A bleed port added to the master cylinder body enables bleeding without removing the lid.
