Why Choose the KMC MissingLink CL710 Connector?

The KMC MissingLink-KOOL CL710 is a reusable quick-link connector built for single-speed and fixed-gear chains running the standard 1/2" x 1/8" pitch. The MissingLink system eliminates the need for a chain tool entirely: snap the link closed by hand, apply light back-pressure through the drivetrain to seat it, and you're ready to ride. Compact and feather-light, it slips easily into a seat bag or jersey pocket as a reliable backup for emergency repairs on any single-speed or track setup.

KMC's KOOL connector design adds a touch of color to an otherwise utilitarian part, making the link easy to identify on the chain at a glance and simplifying removal during routine cleaning. The CL710 is compatible with KMC and most standard 1/2" x 1/8" single-speed chains, covering everything from urban commuters and fixies to track bikes and single-ring gravel setups. A practical, no-fuss upgrade for any single-speed rider who wants tool-free chain access whenever maintenance calls.
