|This is the best way to connect your chain. Unlike other chain connectors, this is reusable, and will last the life of your chain. It has a built in wear indicator so you know when to replace the link and the chain. The Superlink is stronger than any regular link in your chain and is competition tested. We have several versions: 9 speed Shimano, SRAM, and Campagnolo 9 speed; Shimano 10 speed; and Campagnolo 5.9mm 10 speed chains (0340).
