42t Campagnolo Gran Sport Vintage Chainring

Most of our chainrings are used but we only keep ones with life left in them, and they are accurately graded depending on physical wear.

3/32" is used for double & triple chainsets but can also be used for single ring chainsets. 1/8" is generally used for track chainsets & some single chainsets too.

Please be sure to check that the BCD (Bolt Circle Diameter) matches that of your crankset, otherwise the chainring will not fit. If you need help measuring your BCD, good ol' Sheldon Brown will be glad to be of assistance here: http://www.sheldonbrown.com/gloss_bo-z.html
