With a double-locking, 16 mm thick square parabolic shackle, the ABUS Granit Extreme 59 gives 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 manipulation such as picking. When transporting, the Granit Extreme 59 is very flexible: you can attach it to 12-17 mm thick tubes using the SH 59 holder or utilize the GIVI Monolock adapter plate M6M as a fully integrated mounting option.
