Kryptonite New York Chain with Evolution Series Disc Lock

At 8.8 lbs, this is a substantial lock designed for security over portability. It is best suited for riders who leave their bike in one high-risk location for long periods, rather than those who need to carry it on their bike frame every day.

The cinch-loop allows you to use the length of the chain more efficiently. By looping one end through the other, you can secure your bike to a wider variety of objects, like thicker poles or trees, without needing a longer, heavier chain.

Yes, the durable nylon sleeve acts as a buffer between the hardened steel links and your bike's paint job. It effectively prevents the chain from scratching or chipping your frame during daily use.

Kryptonite offers a Key Safe Program where you can register your key number online. If you lose your keys, they can send replacements directly to you, so be sure to record your key number as soon as you receive the lock.

Absolutely. The lock is designed to be weather-resistant, and the protective nylon sleeve helps keep dirt and moisture out of the chain links. Just be aware that extreme cold can occasionally make any lock mechanism stiff, so keeping it lubricated is a good practice.

The 1000 mm (roughly 3.3 feet) length is standard for most urban locking scenarios. It provides enough slack to secure your frame and one wheel to most standard bike racks, though it may be tight if you are trying to secure both wheels and the frame simultaneously.
