Hope RX4+ SL Brake Caliper | Flat Mount +20mm | MIN - purple

Built for adventure!

The Hope RX4+ SL brake caliper is the successor to the RX4 brake caliper and the result of 25 years of experience Hope have gained in developing hydraulic disc brakes. The stiffness of the one-piece milled caliper enables a positive bite point through efficient transfer of braking force.

New bore cap design decreases overall width of the caliper for better frame compatibility. The monoblock construction results in a stiffer caliper, reducing imprecise braking feel and brake pad rubbing.
