Double security against bicycle theft

It couldn't be easier – with this frame lock chain made of hardened steel, you have the ideal secondary security for your bicycle. The Adaptor Chain 2.0 from ABUS makes it particularly easy to secure your bike twice: simply wrap the chain around a fixed object, pull the end of the chain through the ring and then insert it into the lock housing of the frame lock or the Alarmbox 2.0. You don't need another key, and there's no need to separately lock the shackle. Thanks to the special coating of the ring, the paint of the bicycle remains protected when locking it up. The Adaptor Chain 2.0 is compatible with all ABUS frame locks that have an additional lock housing, as well as the Alarmbox 2.0.
