Campagnolo Comp One Chainset is a carbon chainset with Ove-Torque technology, which combine chainset and bottom bracket with wide stance bearings and a 30mm axle. This results in 5% increase in rigidity over the Campagnolo Record chainset. The chainset is also lighter than before. Campagnolo have also reviewed the profile of the chainring teeth to enhance efficiency and compatibility with the 11-Speed chain and the cleverly-shaped derailleur to contribute to making the movement of the chain extremely quick, even under load.
