Instead of searching for your key, with the Steel-O-Flex™ Tresorflex 6615C it’s simply a case of: select the numerical code you want, set the number reel and secure your bike.

This clever cable lock is full of ABUS quality: the 15mm steel sleeves that envelop the steel cable makes things twice as difficult for thieves.
