Every 10-speed chain eventually needs to come apart. Drivetrain cleaning, cassette swaps, travel bike disassembly, or just replacing a worn chain—the PowerLock link handles reconnection without special tools or the fiddly process of pressing pins back through plates. SRAM designed these as single-use connectors, which means the locking mechanism works once and holds secure, but reusing them after separation risks the plates not seating fully into their locked position.

The PowerLock connects by threading the chain ends through each plate, then pulling the chain taut until the link snaps into place. You'll feel it lock. No chain tool required for installation, though you'll need one to break the chain at a different link first if you're replacing an old PowerLock. The plates are directional—there's a SRAM logo that should face outward on the drive side—but the link works regardless of orientation. It just looks cleaner installed correctly.

Compatibility covers SRAM's full 10-speed chain lineup: PC-1031, PC-1051, PC-1071, and PC-1091. The link matches the width and plate geometry of these chains, so shifting performance stays consistent across the connection point. Using a PowerLock on a different brand's 10-speed chain isn't recommended because plate thickness and roller width vary between manufacturers, and a mismatch can create a stiff link or compromise the lock engagement....
