SwissStop Catalyst Disc Rotor

The SwissStop Catalyst disc rotor has been engineered to provide optimal heat dissipation while providing powerful braking and superior durability. The two-piece design consists of a 7075-T6 aluminum alloy spider and SUS410 stainless steel brake track to balance lightweight with reliable thermal management and structural performance.


  • Optimum heat dissipation
  • Reliable performance for a variety of riding styles, including road, cyclocross, cross country and downhill
  • High durability, even in the toughest conditions
  • Compatible with all sintered and organic pad compounds, but optimized for SwissStop EXOTherm2
  • Vibrations are minimized by the geometry of the brake pad contact area
  • Features wear out indicators - small divots on the surface show when it is time to replace the rotor
