Product description
The Hope RX4+ SL front brake caliper features a flat‑mount design, hydraulic disc operation with DOT fluid, and a four‑piston, 160 mm rotor‑compatible setup. Made from CNC‑machined aluminium, it suits road, cyclocross, and gravel bikes, offering a slim profile for modern frames.
Hope’s RX4+ SL front brake caliper, released for the 2026 model year, combines a flat‑mount interface with a four‑piston hydraulic system that uses DOT 4 or DOT 5.1 fluid. Constructed from CNC‑machined aluminium, the monoblock design provides stiffness and a consistent bite point while keeping the caliper lightweight. The caliper accommodates 160 mm and 180 mm rotors and includes a top‑entry pad layout for easy maintenance. Designed for road, cyclocross, and all‑road/gravel bikes, it integrates with SRAM drop‑bar brake systems, including Red, Force, Rival, and Apex groupsets. The blue‑finished unit offers a 20 mm offset to improve frame compatibility, delivering reliable stopping power across a range of riding conditions.
