Kryptonite Evolution

The toughest bicycle security for moderate to high crime areas, the Evolution U-lock has a half-inch (13mm) through-hardened Kryptonium™ steel shackle. It features a high-security, disc-style cylinder that has a center location, which defends against leverage attacks. This lock has a reinforced sleeve over the crossbar and cylinder providing additional security. Included are: anti-rattle bumpers to noise reduction during transport, lighted key for nighttime use, a rotating dustcover to protect the cylinder and the EZ Mount transportation bracket. The Evolution is part of the Key Safe program and can be paired with a KryptoFlex® cable for quick-release component and accessory lock up.
