The Hope Tech 4 EVO GR4 is a four-piston gravity brake built for demanding applications, including downhill, enduro, and e-bike use. It delivers maximum power with a smooth, predictable lever feel. This brake stands as a benchmark for severe riding conditions, providing reliable control.
This brake features the largest pistons in Hope's lineup, increasing power by 6% compared to the Tech 4 V4 system. A new cam mechanism reduces free lever stroke while maintaining modulation. Its one-piece machined caliper offers increased stiffness and a revised bore cap provides more frame clearance.
