High-Security U-Lock for Daily City Use
The Kryptonite Evolution Series U-Lock (3 x 9.5") is built for riders who park in real-world city conditions and need a lock that can stand up to serious attacks. Its 13 mm hardened max-performance steel shackle resists bolt cutters and leverage, while a compact 3.25" x 9.5" interior gives would-be thieves less room to work.
A hardened double deadbolt and high-security disc-style cylinder make twist attacks and picking far more difficult, and the sliding dust cover helps keep grit out of the keyway for smoother operation over years of use. The included FlexFrame bracket lets you carry the lock on the bike instead of in a bag, making it a practical choice for daily commuting and urban errands.
