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.
