Kryptonite New York Chain Evolution Series Disc Lock

This is a heavy-duty security chain, so it is substantial in weight. While it provides excellent protection, it is best suited for riders who can leave it locked at their destination or who don't mind carrying significant weight in a pannier or backpack during their commute.

No, the chain is encased in a durable nylon sleeve designed specifically to prevent the metal links from scratching or damaging your bike's paint and frame.

The 66-inch length offers significant versatility, allowing you to secure your frame and rear wheel to most standard bike racks or poles. However, securing both wheels and the frame simultaneously may be difficult depending on the size of your bike and the object you are locking to.

The double deadbolt mechanism locks both sides of the shackle into the crossbar. This design is crucial because it requires an attacker to make two separate cuts to break the lock, significantly increasing the time and effort needed to compromise it.

Yes, the included lighted key is very useful for finding the keyhole quickly when locking or unlocking your bike in dark parking areas or at night, saving you from fumbling in the dark.

Yes, Kryptonite offers a key replacement program. Be sure to register your key number with them immediately after purchase so you can easily order replacements if needed.
