Description

The HOPE RX4+ SL Flat Mount 34mm DOT hydraulic brake calliper has been designed by the British brand to be paired with a Sram road brake lever. It is intended for front Flat Mount 34 mm fitting with a 160 or 180 mm disc (with adapter), or front Flat Mount 70 mm fitting with a 140, 160 or 180 mm disc with adapters. It can also be fitted as rear Flat Mount 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 be fitted to 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 monoblock construction that transmits braking force very efficiently, with no poor feedback 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.
