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

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 we’ve 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.
