Designed for high-performance braking, this well researched and developed brake rotor offers reliability across a range of cycling disciplines and shows superb durability, even in the harshest of conditions.

Adding strong and efficient stopping power to road and MTB riders, the Catalyst has gone through stringent lab testing to ensure it excels with longevity, thermal management, shorter stopping distances, wearability and structural integrity. The end result is a rotor which provides an impressively high-level of performance, no matter how challenging your ride gets.

Made up of two pieces - a 7075-T6 aluminium alloy spider and SUS410 stainless steel brake track - the perfect balance of structure and thermal management is met, while the geometry of the brake pad contact area significantly reduces vibrations for a smooth engagement. Equipped with wear out indicators and free from sharp, 90-degree edges, this meticulously crafted disc brake rotor from SwissStop brings an excellent braking experience, however you ride.
