Description
The HOPE RX4+ SL Flat Mount Front (+20) Mineral hydraulic brake calliper was designed by the British brand to be paired with a Shimano/Campagnolo road brake lever. It is intended for a Flat Mount front 70 mm fitting and is designed to equip a classic road bike or a cyclocross bike, with a 160 or 180 mm disc depending on the fork offset.
Thanks to its 4-piston system, it provides powerful and safe braking. This calliper benefits from a rigid monoblock construction that transmits braking force very efficiently, with no adverse sensation at the lever.
The RX4+ SL (2026) features a narrower bore cap, inspired by the GR4 and TR4 models, reducing the width of the calliper and improving compatibility with more frames. It also incorporates the bleed nipple from the RX2, making the bleed simpler and cleaner. These targeted improvements make the RX4+ SL more user-friendly, whilst retaining the performance and reliability expected of RX4+ brakes.
