Hope RX4+ Caliper Post Mount - Mineral Version 2024

The Hope 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 machined from 2014 T6 Aluminium results in a stiffer caliper to give unrivalled feel and modulation.  This RX4+ caliper is only Mineral compatible (Shimano/Campagnolo systems) and is available in 6 colours (Blue, Orange, Red, Black, Purple, Silver) and comes with 2 sets of brake pads (Blue for road use and Red for Cyclo Cross andd Gravel use).

This version of the RX4+ caliper is made for Post Mount and allows the installation of 160 and 180 mm rotors depending on the frame / fork mount and the adapter
