HOPE brake caliper RX4+ Postmount for SRAM | DOT
HOPE has the right brake solution for gravel bikes and road bikes in its range. Proven English milling skills combined with technical understanding have resulted in the HOPE RX4+ brake caliper. The current version boasts larger pistons (2x 14 mm and 2x 16 mm to 2x 11 mm and 2x 14 mm), an improved angle of the brake hose connection and new mounting options for the flat mount standard.
According to HOPE, the RX4+ brake caliper in monobloc design is perfectly machined from a single piece, which not only leads to increased performance compared to two-piece solutions, but also prevents unwanted rubbing or "rubbing" with the matching pads and rotors, while simultaneously improving the pressure point. Another advantage is the four-piston solution, with two smaller and two larger slave pistons. The two smaller ones lead to quick application of the Brake Pad, while the two larger ones maximize the braking force. This allows you to finely regulate the braking force even on difficult surfaces.
The HOPE RX4+ brake caliper fits all current SRAM hydraulic road bike brake levers, the replacement is very simple, as you only have to replace your existing brake caliper with the HOPE RX4+ brake caliper. This means you can update all SRAM road bike groupsets (Red, Force, Rival and Apex) to the HOPE RX4+ brake caliper.
Note: HOPE RX4+ brake calipers are only approved for the DOT 4 and DOT 5.1 brake fluid used by SRAM!
