A hard nut for thieves to crack: the GRANIT 460 U-Lock cannot be bent open or attacked using ice spray.This U-lock has a lot to offer: the 12mm parabolic shackle, the housing and the load-bearing parts of the locking mechanism are manufactured using specially hardened steel. When combined with the Abus Extra Class cylinder, they result in a lock which can rightly be considered the safest way of securing high-value bicycles. The locking mechanism is a standout feature: not only is it particularly secure thanks to the double locking system, but it is also supplied with a coded reversible key. By ordering other locks which are coded appropriately all of the locks owned by the members of a single family can be operated using one key, for example. ¢ Hardened 12 mm parabolic shackle¢ The shackle, the lock body and the structural parts of the locking mechanism are manufactured using specially hardened steel¢ ABUS Extra Class cylinder with coded reversible key
