Description

The HOPE RX4+ SL Flat Mount 34mm DOT hydraulic brake calliper was designed by the British brand to be paired with a Sram road brake lever. It is intended for Flat Mount front 34 mm mounting with a 160 or 180 mm disc (with adapter) or Flat Mount front 70 mm with a 140, 160 or 180 mm disc with adapters. It can also be mounted as Flat Mount rear 34 mm with a 140 mm or 160 mm disc (with adapter) and depending on the rear offset with a 180 mm disc.It is designed to equip a classic road bike or a cyclocross bike.

Thanks to its 4-piston system, it delivers powerful and safe braking. This calliper benefits from a rigid monobloc construction that transmits braking force very efficiently, with no poor 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 integrates the bleed nipple from the RX2, making bleeding simpler and cleaner. These targeted improvements make the RX4+ SL more user-friendly, while retaining the performance and reliability expected of RX4+ brakes.
