Hope RX4+ SL Caliper Complete - FM+20 - MIN - Silver

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

Designed specifically for mineral oil brake systems, the RX4+ SL is the ideal upgrade for Shimano and Campagnolo hydraulic road and gravel groupsets. Its four-piston design provides significantly increased braking power and control compared to conventional two-piston calipers, making it particularly well suited to gravel riding, bikepacking, endurance road riding and demanding descents.

The RX4+ SL features Hope's latest slimline caliper design, reducing the overall width of the caliper to improve clearance around modern road and gravel frames. A redesigned bore cap arrangement also improves servicing and bleeding access while maintaining the outstanding performance and reliability that has made the RX4+ a benchmark upgrade for hydraulic road disc brakes.

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