Beef up your bike protection with the Kryptonite KryptoLok Series 2 995 Integrated Chain Lock. As formidable an opponent to thieves as it looks, this lock's chain links are made of hardened Manganese steel for maximum strength against attacks, while the durable, protective nylon cover with hook-and-loop fasteners keep the chains underwraps for protection against scratches to your frame and resists water for longevity. The hardened deadbolt locking system boosts the lock's overall holding power, which is secured by the patent-pending End-Link design to eliminate critically vulnerable spots. Drills and picks are useless against the reinforced, high-security disc-style cylinder.
