The Hope Tech 4 EVO GR4 Right-Hand Brake Lever and Calliper is designed for riders who demand uncompromising stopping power in the most extreme conditions. Ideal for gravity, enduro, and e-bike applications, this four-piston brake system combines maximum power, super-smooth lever action, and premium construction to give total confidence on steep and technical terrain.
The new cam mechanism reduces free lever stroke while maintaining precise modulation, allowing riders to feel completely in control at all times. The pistons benefit from an additional secondary guide bush, ensuring perfectly straight movement and smooth, consistent braking performance.
Bleeding the system is simple thanks to the newly added bleed port on the master cylinder body, which allows maintenance without removing the lid. The one-piece machined caliper enhances stiffness while reducing weight, and the four hybrid pistons provide excellent heat management for sustained braking on long descents. The largest pistons ever fitted to a Tech 4 brake increase braking ratio by 6% compared to the V4 system, delivering phenomenal power while improving modulation and control.
The redesigned bore cap reduces overall width, offering better frame clearance, while the increased caliper stiffness ensures precise braking under the most demanding conditions. Please note, this system is not compatible with vented rotors.
For riders seeking the ultimate in control and power, the Hope Tech 4 EVO GR4 sets the benchmark for gravity and e-bike braking performance.
