The lock of Abus is stable, solid, yet not as hard as some other chain locks. The chain and, above all, the padlock is right in its dimensions and not so bulky. Above all, the castle and the chain is coated with plastic and protected the key insertion against rainwater. With a length of 110 cm, you can attach the rear wheel and frame easily to a fence or road sign. Security against theft is sufficient in my view completely out. Who has cracks this chain lock and the tool for the bigger brothers in the pocket.
