RX4 Rear Flat Mount

The RX4 caliper 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. Choose from Shimano or Sram depending on your lever.
