What Makes the Kryptonite Evolution U-Lock Worth It?

The Kryptonite Evolution Series U-Lock delivers high-security protection built around a 13mm MAX-Performance hardened steel shackle that resists bolt cutters and leverage attacks. A secure disc-style cylinder resists picking and drilling, while the short crossbar and compact shackle design minimize the exposed metal a thief can work with. This lock ships with a 4-foot braided steel cable, so you can secure both wheels without a second lock.

The double deadbolt locking mechanism engages on both sides of the shackle for added rigidity, reducing the leverage point available to attackers. Dimensions of 3.25 x 7 inches give you enough internal clearance to fit most frame and rack combinations. Backed by Kryptonite's anti-theft protection offer, this is a reliable daily-use lock for cyclists who park in moderate-to-high-risk areas and want real peace of mind.
