About this product
The Hope RX4+ SL is a front flat mount hydraulic disc brake caliper designed for use with DOT-type hydraulic fluid. It features a CNC-machined monobloc design that increases stiffness for precise lever feel and reduces pad rub. Made from 2014-T6 aluminum, the caliper is lightweight yet strong. The slimline 4-piston setup delivers reliable and powerful braking performance. Updates include a narrower bore cap design to improve compatibility with more frames and a bleed nipple design from the RX2 model, allowing for easier and cleaner bleeding. The caliper also has a top-entry pad fitting for quick and simple pad removal or installation. It fits 140mm, 160mm, and 180mm rotors. Rotor is not included. The caliper is finished in silver.
