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


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

And once you have adjusted the number reel after closing the lock, the sleeve-covered steel cable of the Steel-O-Flex™ Tresorflex 1355 effectively protects your bicycle from theft. 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.


  • 15 mm thick, overlapping steel shells protect the internal steel cable
  • Plastic coating to prevent damage to the bicycle’s paintwork
  • Two-component number reel guarantees life-long visibility of the digits
  • Special touch protection for increased security against unauthorised access to the code through manipulation of the mechanism
  • Dark-touch function facilitates use in the dark thanks to special imprinting

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. ...
