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 light weight 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
