Shimano SM-RT86 Rotor Info
The Shimano SM-RT86 Rotor is a centerlock disc brake rotor built from stainless steel with a two-piece construction that bonds the braking surface to an aluminium spider — reducing rotational weight while maintaining the durability expected from Shimano's XTR-tier components. Designed for mountain biking and demanding trail riding, it delivers consistent stopping power across a range of conditions.
The two-piece design isn't just about weight. By isolating the steel braking surface from the aluminium carrier, the rotor is better able to dissipate heat under heavy braking loads — a meaningful advantage on long technical descents where brake fade can become a real concern. Available in 160mm, 180mm, and 203mm diameters, you can match rotor size to your riding terrain and brake setup.
