Purpose-built for SRAM's 1x11 mountain drivetrains, the PC-X1 chain applies XX1 geometry at a price that matches the X1 and GX groupset tier. The chain uses solid pin construction, an 11-speed PowerLock connector, and shifting profile that SRAM developed for the XX1 platform . If you're running an X1, GX, or NX 1x11 drivetrain and need a chain that matches the original spec without stepping up to the hollow-pin XX1 version, this is where SRAM lands the price and durability balance.

The solid pin construction is the main difference between the PC-X1 and the higher-tier XX1 chain — you give up a bit of weight savings, but the trade-off is a chain that handles the wider cassette ranges and cross-chaining of 1x setups without sacrificing pin strength. Chrome-hardened finish on the plates and pins, cut-out side plates, and flush rivets carry over from the XX1 geometry , so shifting quality across an 11-speed cassette stays consistent with what SRAM's higher-tier chains deliver.

The PowerLock connector included in the box handles installation without a chain tool. SRAM designed PowerLock as a tool-free connection method, but the tight tolerances of 10- and 11-speed drivetrains mean each PowerLock is a one-time application — plan on a fresh one every time you break the chain.
