About this product
The Hope RX4+ rear disc brake caliper features a flat mount design and uses DOT hydraulic fluid. It is CNC-machined from 2014-T6 aluminum for high strength and reduced weight. The monobloc construction creates a stiffer caliper, improving brake feel and modulation while reducing lever fuzziness and brake pad rub. This slimline four-piston caliper delivers reliable and powerful braking. It is fully serviceable to extend its lifespan. The top-entry pad fitting allows for quick and easy pad removal or installation. The caliper is compatible with 140mm, 160mm, and 180mm rotors. This model comes in red and does not include a rotor.
