The 12 mm thick round shackle made of specially hardened steel provides reliable protection for your two-wheeler at all times. With its solid construction and high-quality lock cylinder, the U-lock offers robust security, which is also confirmed by the Sold Secure Silver test seal. Thanks to the supplied SH34 holder, the U-lock can be conveniently and easily transported on your bike without any annoying rattling. In combination with the Cobra cable, the Ultra 410K can also be used to secure other components such as tyres in addition to the bike frame. The newly designed lock body casing combines improved materials with proven signal colour or is available in the Special Edition with the new Flakeberry Purple material finish.
