Kryptonite's Evolution Series 4 1016 Integrated Chain is a 10mm-thick, six-sided link chain made of triple-heat-treated, boron-manganese steel for maximum strength. At over five feet long, the Evolution gives you plenty of chain to lock up multiple bikes. It uses an integrated high-security cylinder that is pick, drill, and cut resistant. The links are covered with a weather-resistant nylon sleeve that protects your bike's finish. 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.

This Kryptonite Evolution Series 4 lock is a MONSTER of a chain lock. We use it to lock our bikes to our receiver hitch bike rack. And we use it to lock our bikes down at Ocean City Maryland. I sleep just fine with the bikes locked up outside with this lock. With the 5.25 foot, 10mm, 6 sided chain and that dead bold lock my bikes are safe. Also, if they get through this chain lock, well, then they deserve the bikes. One thing this chain lock is heavy!
