SwissStop Catalyst Centrelock Disc Brake Rotor - 203mm - Centrelock PLP|EMTB Optimised Top Head Tube Inside Diameter:You probably thought all Rotors were the same right? Well, not the Catalyst centerlock rotor from SwissStop. In 2015 some pretty smart engineers did a lot of testing of all the main rotors on the market and analysed the results.

Less brake fade, shorter stopping distances, slower wear
