Hope RX4+ Disc Brake Flat Mount

The RX4+ caliper supersedes the RX4 caliper and builds on 25 years’ experience designing and manufacturing hydraulic disc brakes and transfers the knowledge and skills acquired into the world of Road and Cyclocross dropbar brakes. A precision CNC machined monobloc design results in a stiffer caliper to give unrivalled feel and modulation.

• Front +20, typically for 160mm rotor but depends on your fork
• Rear +20, typically for 160mm rotor but, again, depends on your frame.
• Both models direct mounting with no adapter required if you aren't sizing up on the rotor diameter
• Use only with DOT fluid, meaning SRAM drop-bar brake levers.
• 4-piston monobloc design is especially stiff.

If unsure please consult this chart to determine compatibility with your frame.
