Hope RX4+ SL Caliper Complete - FM+20 - DOT - Blue

The Hope RX4+ SL is the latest evolution of Hope's acclaimed 4-piston road and gravel brake caliper, delivering exceptional stopping power, improved modulation and enhanced frame compatibility. CNC machined from a single piece of 2014 T6 aluminium, the monobloc construction creates a stiffer caliper body for a firmer lever feel, reduced pad rub and consistent braking performance across all riding conditions.

Designed specifically for DOT fluid brake systems, the RX4+ SL is an ideal upgrade for SRAM hydraulic road and gravel groupsets. The four-piston design increases braking power and control compared to conventional two-piston calipers, providing confidence-inspiring performance on steep descents, technical gravel routes and fully-loaded adventure bikes.

The RX4+ SL introduces a revised slimline design that reduces the overall width of the caliper, improving clearance around modern road and gravel frames where space can be limited. The updated bore cap arrangement also improves serviceability and bleed access while maintaining the renowned performance and reliability of the original RX4+.

This FM+20 version is designed for Flat Mount frames and forks requiring a +20mm offset, making it suitable for larger rotor applications without the need for additional adapters in compatible installations.
