Description

For 2026, the RX4+ has been refreshed as the RX4+ SL, featuring 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 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.
