Twelve-speed chains require narrower tolerances than their 11-speed predecessors, which makes having the right quick link on hand essential. The MissingLink 12 CL552 from KMC provides tool-free chain connection for 12-speed drivetrains, allowing you to join a new chain or make trailside repairs without a chain tool. The 2-pack gives you one connector for installation and a spare for your saddle bag or home workbench.

Compatibility spans the major 12-speed ecosystems. The CL552 works with KMC, Shimano, SRAM mountain bike, and Campagnolo 12-speed chains, covering road, gravel, and mountain applications regardless of which brand chain you're running. This cross-compatibility makes it a practical spare to carry since it handles most 12-speed scenarios you'll encounter.

The Ti-N (Gold) version features a titanium nitride coating that adds surface hardness and corrosion resistance beyond the standard nickel-plated Silver option. Both versions install the same way: slide the two halves together through the chain ends, align the pins in the outer plate slots, and apply pedal pressure to lock the link into place. These are single-use connectors, so once installed they shouldn't be removed and reinstalled. If you need to remove your chain regularly for waxing or deep cleaning, consider the reusable DLC version instead.
