You can be assured, it is steel used by the German mark, ABUSE, quality home since 1924! The metal is coated with a synthetic fiber that allows not to damage part of your 2 wheels and protect the closing mechanism. A removable valve prevents water from penetrating into the lock. I especially liked the shape of symmetric keys (not round), overall size that fits very well to the big bikes, the matte color of the coating and the impressive diameter of the handle !!! The only downside might be its weight. 1,6kg is 500g more than its direct competitor in STRONGMAN (shorter and wider). Between the two, it is up to you but this model ABUS 501 is undeniably more deterrent. He must!
