Product Details
Hope RX4+ Caliper Postmount Min - Black
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.

The following calipers will now be available.
