Hope RX4 Complete Caliper

The Hope RX4 Complete Caliper features 4 lightweight, Slimline pistons for optimum braking performance and is compatible with SRAM or Shimano drop bar Road brake levers. This brake caliper is aimed at Road and Cyclocross riding and provides exceptional braking power and modulation feel at the levers. Thanks to the 4-piston design, it uses larger brake pads, which have a greater contact patch with the disc rotor and ensure more effective control, and braking performance while dissipating heat much faster.


  • Compatibility: SRAM or Shimano hydraulic drop bar (Road) brake levers
  • Pistons: Slimline 4 piston
  • Construction: Monobloc
  • Note: does not fit IS mounts
  • Weight: 123g (Post Mount)
