The Hope GR4 is a four-piston gravity brake for the most demanding applications delivering maximum power with no compromise. Super-smooth lever action and premium construction make controlling that power feel natural. The benchmark brake for gravity and e-bike use.
- 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
- New cam design decreases the free lever stroke while maintaining the feel and modulation in the braking zone
- Features a roller bearing main pivot and 2 guide bushes to keep the piston running perfectly smooth and straight
- One-piece caliper design for the best stiffness to weight ratio that results in improved lever feel and increased power (NOTE: GR4's are not compatible with vented rotors)
- Larger pistons increase the ratio of the brake for more power
- New bore cap design decreases overall width of the caliper for easier packaging and better frame compatibility
- Larger adjustment range for better compatibility with third party hubs and frame combinations
- Bleed port added to the master cylinder body enables bleeding without removing the lid
