The Hope RX4+ DOT type brake caliper has been refreshed as the RX4+ SL. The RX4+ SL caliper retains a precision CNC-machined monobloc design that results in a stiffer caliper to give unrivaled feel and modulation. In addition it now features a new bore cap that adopts the narrower design first introduced on the GR4 and TR4 to reduce overall caliper width and improve compatibility with a wider range of frames. It now also incorporates the bleed nipple design from the RX2 making bleeding simpler and cleaner. Together these focused updates make the RX4+ SL more user-friendly while maintaining the powerful reliable performance riders expect.
