The KryptoLok Series 2 ATB U-lock’s extra width makes this the standard for mountain bike security. With a reinforced steel shield over the crossbar and cylinder, enhanced security to internal functions comes standard. The 13mm hardened Performance steel shackle resists cutting and leverage attacks, while the high-security disc cylinder resists picks and drills. Two “I” keys, one of which features an LED light for locking and unlocking in the dark, are included with this reliable U-lock. The KryptoLok Series 2 ATB is 5 x 9-inches and has an anti-theft protection offer.
