Flexible Chain Security for Everyday Lock-Ups The Kryptonite KryptoLok Series 2 912 Integrated Chain gives you solid, real-world bike security in a flexible format that is easy to route around racks, posts, or railings. With 4 feet (120 cm) of chain, it is long enough to secure your frame and a wheel without leaving a lot of extra slack for would-be thieves to work with. 9 mm, four-sided links made from 3T manganese steel resist common hand tools, while the integrated lock head with talon deadbolt eliminates a traditional “weak link” shackle. A weather-resistant nylon sleeve keeps your frame protected from scratches and makes the chain more comfortable to carry in a pannier, basket, or over your shoulder. Built to Last 9 mm four-sided chain links made from 3T hardened manganese steel for strong cut resistance. Integrated KryptoLok Series 2 lock head with talon deadbolt and pin-less link design to remove weak points. High-security disc-style cylinder that is pick- and drill-resistant for added peace of mind. Weather-resistant nylon sleeve helps prevent frame damage and keeps the chain quieter in transit. Compact coiling makes it easy to stash in a pannier, basket, or cargo bike box. Includes two ergonomic stainless steel “I” keys and access to Kryptonite’s Key Safe Program. Security rating of 6/10: well-suited for moderate-risk areas and shorter to medium lock-up times.
