Kryptonite Evolution Series 4 1055 Mini Integrated Chain Lock Black/Orange, 55cm

The Kryptonite Evolution Series 4 1055 Mini Integrated Chain Lock might look petite at first glance, but don't let its small statue fool you, it packs a serious punch. It's made from burly 10-millimeter, six-sided, 3T manganese steel links that withstand cutting and shattering with resilience, and then wrapped in a weather-resistant nylon sleeve. The nylon sleeve is weather resistant, so it protects your chain from rusting away in wet climates, while shielding your frame from dents and scratches that can be caused by a heavy-duty chain. Kryptonite's designers use a patent-pending end link design that secures the chain to a hardened deadbolt, reducing vulnerability in what can otherwise be a weak point in a lock, and they employ a high-security disc-style cylinder that is both pick and drill resistant to stand up to conniving bike bandits.
