Engineered for serious security, this Chain Bicycle Lock combines brute strength with advanced anti-theft technology to keep your bike exactly where you left it. Built with 10 mm six-sided 3T manganese steel chain links, it resists cutting, leverage, and attacks that lesser locks can’t withstand.

A patent-pending end link design secures the chain directly to a hardened deadbolt, eliminating the weak link found in standard chain locks. The pick and drill-resistant high-security disc cylinder pairs with a patented reinforced oval crossbar lock head for next-level protection.

Wrapped in a durable, weather-resistant nylon sleeve, this lock not only stands up to the elements but also protects your frame from scratches. Includes 3 stainless steel keys, and access to a Key Safe Program for added peace of mind if you ever need replacements.
