Shimanos XT Brake Rotor, the SM-RT86, sets itself apart from Shimanos 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 Shimanos 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.
