Kryptonite Evolution Series 4 1090 Integrated Bike Chain Lock

Kryptonite's Evolution Series 4 1090 Integrated Chain is a 10mm-thick, six-sided link chain made of triple-heat-treated manganese steel for maximum strength. At 35.5-inches long, the Evolution gives you biking security in an easy-to-carry package. The links are covered with a weather-resistant nylon sleeve that protects your bike's finish, and it uses an integrated high-security cylinder that is pick, drill, and cut resistant. Three keys are included, including one that has a high-intensity LED bulb for convenient, easy unlocking in the dark. This chain has an anti-theft protection offer of $2,250, too.

End link design secures chain to hardened deadbolt offering no weak links in the chain.
