Kryptonite Evolution Integrated Chain

While the exact weight can vary slightly, this chain is built with 10mm hardened manganese steel, making it substantial and heavy. It is designed for high-security, stationary locking rather than for riders looking for an ultra-lightweight, portable solution.

Yes, the 1200mm (approximately 4 feet) length provides enough slack to secure your frame and one wheel to most standard bike racks, lamp posts, or parking meters. It offers more flexibility than a U-lock, allowing you to lock up in tighter or more awkward spaces.

No, the chain is encased in a durable, weather-resistant nylon sleeve. This protective cover prevents the steel links from making direct contact with your bike's paint, keeping your frame free from scratches and dings.

Standard chains often have a weak point where the chain connects to the lock head. This model uses a patent-pending end-link design that secures the chain directly to the hardened deadbolt, eliminating that common vulnerability and making it much harder for thieves to pry or twist the lock open.

The lock features a sliding dustcover that shields the disc-style cylinder from dirt, rain, and road debris. While it is weather-resistant, it is still good practice to occasionally lubricate the cylinder with a silicone-based spray to keep the mechanism operating smoothly.

Kryptonite offers a Key Safe Program that allows you to register your key number online immediately after purchase. If you lose your keys, you can order replacements directly through their program, so be sure to write down your key code and store it in a safe place.
