Sram Disc (without lock nut) Paceline Centerlock 140mm arrondi

The Sram Paceline disc has been designed to achieve a constant center of friction throughout the rotation for reduced vibration, consistent performance and quiet running. To meet UCI safety requirements, Sram has rounded the edges of the discs so that they do not have a 90° angle. This is to reduce the risk of injury in the event of a massive crash in the peloton.Details: Center Lock fastening Rounded edges. UCI compliant. Road and MTB compatible.
