Kryptonite Evolution Integrated Chain 1090 Chain Lock

The “Integrated Chains” from Kryptonite® follow an innovative approach.

The chain and its links are directly connected to the lock cylinder and no longer represent an external part. The advantage: The “Integrated Chains” offer even fewer attack surfaces for thieves and protect your bike even more reliably.
