Developed for no-compromise enthusiasts with performance in mind. The semi-metallic compound and the fine-tuned coefficient of friction provide the best braking control, long pad life, and steady performance at all temperature ranges, in dry or wet. The black series Sinter 550 performance bicycle brake pads are designed for the no-compromise racers, off-road or on-road – while still maintaining long-lasting life! With the fine-tuned, slightly lowered friction coefficient they provide the best braking control, long pad life, and steady performance at all temperature ranges. They ensure excellent control and confidence on slippery and muddy terrain, or at high speeds on the road, in dry or wet conditions. The brake pads are fabricated from the S-550 semi-metallic compound, and they perform best with standard OEM non-floating or floating brake rotors.Features:- Performance- Long-Lasting Life- Best Braking Control In All Temperature Ranges- Mud, Rain Friendly
