Features & Benefits N/A Includes Housing, Disc, Hub, Calipers, and Facings N/A
  • XTB multi-caliper tension control brakes maximize heat dissipation by deflecting it away from rotor the brake components
  • Fins on the rotor, hub back and calipers to throw dissipated heat into space, not into the brake
  • The fin design also draws cooler air around and over the brake
  • Thermal capacity up to 60 horsepower with a dual rotor
