Kryptonite introduces the Evolution Series 4 Integrated Chain for convenient bicycle protection in moderate to high crime areas. The hardened 3t manganese steel chains include 10mm six-sided links. The integrated chains secure with a new patent-pending integrated Evolution series 4 lock head.In the early 1970s, Michael Zane was a free-spirited, bearded kid with a VW van and a big idea for a new kind of lock. He traveled thousands of miles showing the unique U-shaped locking device and spreading his passion for bicycle security to bike dealers all around the country and forged lifetime relationships. The company soon expanded its product line to include powersports, hardware and snowsports security.
