Catalyst One Rotor 160mm Center Lock

The SwissStop Catalyst One is a one-piece disc rotor built around SwissStop's Catalyst brake ring, sized for use across road, cyclocross, cross country, and downhill riding. Rounded outer edges meet UCI approval standards for road racing at select sizes. Three small holes per side mark when the rotor has worn down and needs replacing.

This rotor uses a splined interface rather than a six-bolt pattern, letting it thread directly onto a matching hub or adapter. It works across a range of common brake pad compounds and caliper systems. Consistent thickness through the braking surface supports even heat dissipation during sustained braking on long descents.
