On 1 January 2017, the Union Cycliste Internationale (UCI) launched the second trial phase for disc brakes in road cycling. For this purpose, the brake discs must not have 90° edges on the outer side. The SwissStop Catalyst discs were approved for road racing due to their rounded edges on the outer side.
