The Kryptonite KryptoLok Series 2 U-Lock is a midweight U-Lock blending the performance of the Evolution series and the original KryptoLok U-Lock to keep your pride and joy secure in medium-high risk areas (think bike storage locations). It features a new hardened double deadbolt to provide increased security against torsion and a high-security disc-style locking cylinder that’s tamper and drill resistant. The shackle has been constructed from hardened steel to provide resistance to tampering, while the KryptoLok Series 2 benefits from Kryptonite’s all-new double deadbolt design to provide additional resistance to high torsion attacks. Handily, Kryptonite have included their FlexFrame-U Bracket to maximise your convenience – now you can transport your Kryptonite KryptoLok Series 2 U-Lock on your frame.
