SwissStop Catalyst disc rotors deliver consistent brake torque over long durations where others experience gradual decline and brake fade. Due to extremely efficient thermal management, Catalyst provides notably shorter stopping distances with very low wear rates under hard braking, exceeding the current industry leaders.

• Optimum heat dissipation for maximum braking endurance and shortest stopping distances
• the original Catalyst that set new standards for performance and durability
• two-piece construction
• Aluminium alloy spider provides increased stiffness
• brake ring thickness is optimised and specific to each diameter
• used by top road, mountain and cyclocross teams
• 6-bolt mount
• can be used with adapter for Centerlock hubs

Compatible with all sintered and organic pad compounds. Optimised for SwissStop EXOTherm2 and Disc RS.
