Lock Kryptonite Evolution Series4 Long Shackle

The Evolution of security

Kryptonite locks are ready to evolve your lock-up today with the Evolution series double deadbolt design.

Featuring a new double deadbolt design with CNC precision machined shackle tips, the New-U Evolution Long Shackle U-Lock offers enhanced protection against cut and twist attacks. The crescent shaped shackle tips cup an internal bump in the crossbar below the deadbolts, making for a more stable and secure hold.
