Kryptonite New York Cinch Ring Chain and Evolution Series Disc Lock

The cinch ring allows you to loop the chain through itself, which effectively creates a longer locking reach without needing a heavier, longer chain. This design helps you secure your bike to wider objects while keeping the overall weight of your lock more manageable.

At 4.25 feet (51 inches), this chain is versatile but may not reach both wheels and the frame on every bike. It is best suited for securing your frame and rear wheel to a fixed object, or for locking two bikes together in a pinch.

The 12mm triple heat-treated manganese steel is specifically engineered to resist cutting attacks, including bolt cutters and hacksaws. While no lock is completely impenetrable, this is one of the most robust options available for high-theft urban environments.

Kryptonite offers a Key Safe Program that allows you to register your key number online. If you lose your keys, you can request replacements directly through them, provided you have registered your set beforehand.
