Hope RX4+ SL Brake Caliper Postmount - DOT - Smoke

For 2026, the RX4+ has been revised as the RX4+ SL. It features a new brake cylinder cap with a narrower design, first introduced with the GR4 and TR4. This reduces the overall width of the brake caliper and improves compatibility with a wider variety of frames. Additionally, the bleed nipple construction from the RX2 has been adopted, making bleeding easier and cleaner. Thanks to these targeted improvements, the RX4+ SL is more user-friendly while providing the familiar, powerful, and reliable braking performance.

Features:

• New bleed nipple design for easier and cleaner bleeding
• New design of the brake caliper cap reduces the overall width of the brake caliper for better frame compatibility
