Review on 🔒 SRAM PowerLock Chain Connector 11-speed: Silver Pack of 4 - Secure and Reliable Cycling Accessory by Jason Franco

If you've given up on the chain and breaker pins for good, this is for you. Four Pack is a good deal if you catch it at the right time. They are speed sensitive so make sure they match your gearbox. No tool is required to replace them, although a tool is usually required to remove them. The tool (guaranteed to be listed on the item page) is relatively cheap and makes it easy to make changes. If necessary, you can use pliers with small needle jaws, but they're not the best. A circuit breaker is required for initial installation. So if you don't have one or can't borrow one, using a bike multi-tool like the Lezyne, Crank Brothers, or Park Tool is a good buy at this point. The tool can save your cock with all the other gizmos on it. Instructions are available online and Park Tool has some great videos if you need them. As many others have pointed out, I reuse links. At this price, they're easy to throw away after a few uses and take with you on your bike too. They're great for replacing chains as you wax them, making what used to be a bit of a chore easier (and you don't have to hunt for pins).
