What Our Gearhead(R) Experts Are Saying: "I just swapped to the MT805 caliper on my XC bike to clean up the frame with a flat-mount setup. It looks sharp, saves weight, and still gives me the stopping power I need on fast courses."For cross-country riders looking to streamline their setup without sacrificing performance, the Shimano BR-MT805 Caliper is a clean, reliable upgrade. This 2-piston flat-mount caliper is purpose-built for lightweight XC frames and delivers consistent braking with Shimano's trusted mineral oil system. Designed to match XTR aesthetics and compatibility, the MT805 offers a powerful, responsive lever feel when paired with the BL-M9200 lever. It's also optimized for Shimano's newest low-viscosity mineral oil, giving you smoother brake modulation and reliable performance across varied terrain and weather.
