The GRANIT Sledg 77 embodies the essence of ABUS security expertise. Once installed, no one can easily take your bike without authorization. The 13 mm locking bolt made of hardened special steel sends a clear message to thieves. A sliding mechanism in the GRANIT Sledg 77 locks the brake disc as simply as it is effectively. Anyone attempting to acquire your bike using picking methods will soon find themselves sweating, thanks to the ABUS XPlus locking cylinder. Another layer of security is provided by the Memory Cable, which reminds you to remove the GRANIT Sledg 77 before you accelerate after parking. The rubber coating protects the paint during locking and unlocking and ensures a comfortable grip.
