Compatibility & Ideal Use Cases

Compatible exclusively with post-mount brake frames and forks and 6-bolt rotors. Requires low-viscosity SM-LVOIL mineral oil (sold separately); standard DOT or other mineral oils will damage seals and reduce performance. Designed primarily for mountain biking, not BMX use. Ideal for competitive cross-country racers and serious trail riders seeking the absolute lightest brake system without compromising stopping power and modulation. The dual magnesium construction and carbon lever body represent the pinnacle of weight reduction in Shimano's XC brake lineup. The race-tuned design prioritizes responsiveness and minimal rotating mass for competitive advantage. Flexible pad compatibility allows precise tuning for specific racing or trail conditions. The included hose simplifies assembly and ensures system compatibility. Premium pricing reflects top-tier materials and racing-focused engineering. Not suitable for BMX, road, enduro, or downhill applications requiring maximum braking power over weight savings.
