Flexible High-Security Chain for Tough Lock-Ups
The Kryptonite Evolution 4 1016 Chain Lock is built for riders who need serious security and flexible locking options. With 5.25 ft (160 cm) of chain, it is long enough to reach awkward racks, posts, or railings while still keeping slack under control. The 10 mm six-sided links are made from 3T hardened manganese steel, offering strong resistance to cutting and leverage attacks in busy city environments.
An integrated Evolution Series 4 disc-style lock head secures directly to the chain, removing the typical weak point of a separate U-lock shackle. A reinforced oval crossbar, End Link design, and high-security cylinder work together to resist picking, drilling, and twisting. A tough nylon sleeve protects your frame from scratches and makes the chain easier to handle on the daily commute.
