Product Information

Compatible parts are now marked by a letter surrounded by a square box – simply put, if all of your components have the same stamped letter on them, they’ll work together. If you find an item at a lower price with another commercial internet retailer, you will receive it from us at the same price, provided the conditions listed in the link are met. Campagnolo has introduced many changes to its groupsets, resulting in reduced compatibility between generations. So boxed letters (indicating the ranges) will aid you in identifying if your parts are compatible.
