Designed to resist bolt cutters and leverage attacks, the Kryptonite Evolution Mini-5 U-Lock-Double Deadbolt uses a Max-Performance steel shackle and reinforced Cuff Over Crossbar to prevent your bike from growing legs and walking off. The disc-style cylinder delivers high-security protection that is both pick- and drill-resistant, while the Bent Foot shackle makes for quick and easy use when you're in a rush. Kryptonite equipped it with Anti-Rattle Bumpers to reduce noise during transport, and the protective vinyl coating reduces the chance of you scratching your frame's paint job.
