Kryptonite New York Cinch Ring Chain with Evolution Series Disc Lock

The cinch ring allows you to loop the chain through itself, which effectively increases the usable length of the chain. This design helps you secure your bike to wider objects without needing a longer, heavier chain, reducing overall bulk while maintaining security.

At 12mm thick, this is a heavy-duty security chain designed for high-theft areas, so it is substantial. While it offers excellent protection, most riders prefer carrying it in a dedicated pannier or wrapped securely around the frame rather than wearing it around their waist.

Yes, the Evolution Series 4 disc lock is a standalone unit. You can use it as a rotor lock for your bike or motorcycle, though it is primarily designed to be paired with the chain for maximum security.

One of the three included keys features a built-in high-intensity LED light, which is activated by a button on the key head. The battery is replaceable, ensuring you can continue to see the keyhole clearly in dark or low-light conditions.

Yes, 4.25 feet is a versatile length that provides enough slack to secure your frame and one wheel to most standard city bike racks or poles. The cinch ring design adds extra flexibility, making it easier to reach anchor points that might otherwise be too far away.

Yes, Kryptonite includes an anti-theft protection offer with this lock. You will need to register your product on their website after purchase to be eligible for the program, which provides coverage against theft if your bike is stolen due to the opening of the lock by force.
