Kryptonite Evolution Series 4 Integrated Chain Lock

The “Integrated Chains” by Kryptonite follow a security-relevant approach: The link chain is directly connected to the cylinder, so that it is no external part. The advantage is obvious: There are fewer attack surfaces for thieves which increases security.
