Steel-O-Flex 1355/85 KF (Art. no. 28682)


A securely-chained bicycle doesn’t always require a key. The ABUS Tresorflex 1355 protects your bicycle with your personal numerical code.

And once you have adjusted the number reel after closing, the sleeve-covered steel cable of the Tresorflex 1355 protects your bicycle from theft effectively. The touch-protected number wheels prevent the mechanism from being tampered with by unauthorised persons. The wheels are designed in such a way that you can set your individual sequence for unlocking even in the dark. Simply open the lock, swing into the saddle and pedal – all without a key.

At ABUS, the name Steel-O-Flex stands for cable locks with high flexibility and double security. The steel cable is covered in overlapping shells made from toughened steel, like scale armour. As a result, its resistance to attempts to break it open is increased significantly, while its weight only increases slightly and its flexibility remains largely intact. This means that it is easy to attach any vehicle to a fixed object. ...
