Why We Like The Shimano XT SM-RT86 Rotor
Shimano’s XT Brake Rotor, the SM-RT86, sets itself apart from Shimano’s lower-tier offerings through its use of an aluminum core to transfer heat away from the brake caliper. This, combined with the finned heat sinks in Shimano’s XT and XTR-level brake pads, combats heat-related brake fade. We appreciate this construction because it translates to consistent, reliable braking even on long descents.
