The Hope Tech 4 Evo GR4 is the most powerful brake Hope has ever made. Built for gravity riders, enduro, downhill, and e-MTB use, the GR4 features four oversized hybrid pistons and a re-engineered caliper body that delivers 6% more stopping power than the Tech 4 V4. With a revised bore cap for better frame clearance and Hope’s signature smooth lever feel, this is the benchmark brake for ultimate control on the steepest, roughest trails.
