Campagnolo 11-speed chain rings for Super Record, Record and Chorus from 2015. 4-arm. bolt circle: 34 teeth - 112 mm 36 teeth - 112 mm 39 teeth - 112 mm 50 teeth - 145 mm 52 teeth - 145 mm 53 teeth - 145 mm Compatibility note: To ensure the functionality of the mechanical Super Record, Record and Chorus drivetrains, Campagnolo recommends to avoid the use of older components at shifting groups from 2015 on. A distinctive marking, a squared letter as in picture 2, helps recognizing actual shifting components. The letters of the corresponding parts (right Ergopower and rear derailleur / left Ergopower, derailleur, cups and crankset) should match.
