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. â€¢ 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
