Hope RX4 Caliper Complete

Drop bar compatible 4 piston calipers specially designed to work with Shimano or SRAM brake lever master cylinders, aimed for Road and Cyclocross use.


  • Drop bar hydraulic calipers to suit Shimano hydraulic drop bar set ups
  • Slimline 4 piston lightweight design
  • Monobloc design creates a stiffer caliper reducing the fuzzy lever feel and brake pad rub

Shimano Version

  • Postmount:- BR-RS785, BR-R785
  • Mineral Oil Brake Fluid Only


Sram Version

  • The RX4-SR post mount caliper can replace Force, Red and Rival
  • Dot 4 or 5.1 Brake Fluid Only
Andy Nice looking caliper, easy to fit, but not that impressed with performance, seems less powerful than the RS785 it replaced, organic pads are quite noisy compared to Shimano organics too.
