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 & 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.
