Description | The ABUS Ultimate 420K is a high security U lock designed for urban riders who need serious theft protection without stepping into the heaviest lock category. Built around a 14 mm round hardened steel shackle and a hardened lock body, it offers strong resistance against cutting and leverage attacks. A double bolt locking mechanism secures the shackle on both sides, increasing protection in high risk parking situations. The updated design helps reduce rattling while riding, and the included USH bracket allows secure mounting to bike frames with tube diameters between 24 and 35 mm. With Sold Secure Gold approval, the Ultimate 420K is well suited for daily commuting and locking in busy city environments.
