Kryptonite New York Cinch Ring Chain with Evolution Series Disc Lock

The cinch ring allows you to loop the chain through itself, effectively creating a lasso. This maximizes the usable length of the chain and lets you secure your bike to a wider variety of objects without needing a longer, heavier chain.

At 2.25 feet, this chain is relatively short. It is designed primarily for securing your frame to a fixed object, rather than capturing both wheels and the frame simultaneously.

The chain is made from triple heat-treated manganese steel, which is specifically engineered to resist cutting and sawing. While no lock is impenetrable, this system is rated for high-theft environments and offers significant resistance against bolt cutters and hand tools.

Yes, the LED key uses standard, replaceable coin-cell batteries. It is a convenient feature for unlocking your bike in dark alleys or late at night without fumbling for the keyhole.

Yes, the Evolution Series 4 disc lock is a standalone unit. You can use it on its own as a brake rotor lock for motorcycles or to secure other items, though it is primarily paired here with the chain for bicycle security.

Kryptonite offers a registered anti-theft protection program that provides financial coverage if your bike is stolen due to the opening or breaking of the lock. You must register your product on their website shortly after purchase to be eligible.
