With a double-locking, 16 mm thick square parabolic shackle, the ABUS Granit Extreme 59 offers thieves no chance. The shackle and other security-relevant parts of the Granit Extreme 59 are made from hardened special steel. An ABUS XPlus cylinder enhances security against manipulations such as picking. For transport, the Granit Extreme 59 is very flexible: you can attach it to pipes with a thickness of 12-17 mm using the SH 59 holder or utilize the GIVI Monolock adapter plate M6M as a fully integrated mounting option.
