The ADAPTOR CHAIN Classic connection chain is the successor to the tried-and-tested ACH 2.0 and features a newly designed oval loop ring. Its narrower shape makes it particularly easy to thread through spokes or narrow gaps – for even more convenient locking.

Double security: The pre-installed frame lock blocks the rear wheels of the bicycle, but does not prevent the bicycle from being carried away. The connecting chain is the ideal addition for securing the bicycle to fixed objects such as lampposts or bike racks. To do this, simply wrap the ADAPTOR CHAIN Classic around the lamppost, for example, and insert it into the additional lock body of a compatible frame lock or the Alarmbox 2.0 – and your bike is doubly protected. No additional key is required for the insert chain. The frame lock key opens and closes both components.

The hardened steel insert chain is covered with a textile sleeve that protects your bike from paint damage.
