Double protection: The pre installed frame lock blocks the bike’s rear wheel but does not prevent the bike from being carried away. The connecting chain is therefore the perfect addition for securing your bike to fixed objects such as lamp posts or bike racks.

Simply wrap the ADAPTOR CHAIN Classic around a fixed object, such as a lamp post, and insert it into the additional lock body of a compatible frame lock or Alarmbox 2.0. Your bike is then secured in two ways. No additional key is required for the plug in chain. The frame lock key locks and unlocks both components.

The plug in chain is made from hardened steel and features a textile coating to protect the bike’s paintwork from damage.
