I have for sale an unused Campagnolo Centaur CS4-CEX36 UD 10s sprockets 13-26T + Campagnolo Centaur CN9-CEX 10s chain. The chain is new and originally packaged by the manufacturer in an unopened plastic bag. The chain was removed from the box for photos. The cassette is unused and has never been mounted to a bicycle. The cassette and chain boxes show signs of long-term storage.
