Kryptonite New York Legend Chain and Disc Lock

This is a heavy-duty security solution, so it is significantly heavier than standard cable or lighter chain locks. It is best suited for riders who leave their bike locked in one place for long periods or those who don't mind the extra weight in a pannier or backpack.

The 14.5mm links are quite substantial, which makes them difficult to cut but also less flexible than thinner chains. While it will fit most standard bike racks, you should ensure your frame's geometry allows for a chain of this thickness to pass through comfortably.

Yes, the durable nylon sleeve is specifically designed to act as a buffer between the hardened steel links and your bike frame. It effectively prevents the chain from causing scratches or dings during daily locking and unlocking.

This lock is compatible with Kryptonite’s Key Safe Program. You should register your key number on their website immediately after purchase, which allows you to order replacement keys directly from the manufacturer if yours are lost or stolen.

While the lock is built for high-theft urban environments, it is not specifically rated as weather-resistant. It is recommended to keep the lock mechanism clean and lubricated periodically to ensure smooth operation if you frequently use it in wet or harsh conditions.

The double deadbolt design locks the shackle on both sides of the disc lock. This creates a much stronger connection that resists twisting attacks and makes it significantly harder for thieves to leverage the lock open compared to single-sided locking mechanisms.
