What is the SRAM PowerLock Link 10-Speed Card of 4 used for?

The SRAM PowerLock Link is SRAM's tool-free master link for 10-speed chains, allowing clean, secure chain assembly without a chain tool or replacement pin. Each link snaps into place through the chain ends and locks under pedaling load, creating a connection that holds reliably under full drivetrain force. This card of 4 gives you four links per purchase — enough for multiple chain swaps or to keep spares ready in the toolbox and a spare in your saddlebag for trailside emergencies.

Compatible with all SRAM 10-speed chains including the PC-1091R, PC-1071, PC-1051, and PC-1031, as well as most 10-speed chains from other manufacturers that accept a standard master link. Removal requires chain link pliers to disengage the locking tabs. SRAM recommends replacing the PowerLock link each time the chain is removed for the most reliable long-term connection. If you maintain your own 10-speed drivetrain and go through chains regularly, keeping a card of PowerLock links on hand is basic shop prep.
