Very cool upgrade for your Road – Gravel Bike….

We all love a HOPE upgrade, these hydraulic disc brake callipers are awesome. Hand made with superb attention to detail, and they work! Hope is definitely at the top of our upgrade list and these really neat callipers offer the chance of adding a splash of colour.

The RX4+ caliper supersedes the old RX4 model and builds on 25 years experience of designing and manufacturing hydraulic disc brakes. Designed to work with drop bar brake levers, Sram or Shimano models available. Using a monobloc design you end up with a stiffer caliper resulting in fantastic stopping power.
