GRANIT™ 460 SPECIALLY HARDENED STEEL COMBINED WITH FIRST-RATE LOCKING TECHNOLOGY A hard nut for thieves to crack: the GRANIT™ 460 U-Lock cannot be bent open or attacked using ice spray.

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 stand-out feature: not only is it particularly secure thanks to the double locking system, but it is also supplied with a coded reversible key.
