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

Doubly secured: the already fitted frame lock blocks the rear wheels of the bike, but does not prevent the bike from being carried away. The connecting chain is the ideal addition for securing your bike to fixed objects such as lamp posts or bike racks. Simply place the ADAPTOR CHAIN Classic around the lamp post, 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. An additional key is not required for the plug-in chain. The frame lock key opens and locks both components.

The plug-in chain made of hardened steel has a textile coating to protect your bike from damage to the paintwork.

The ST 5950 2.0 saddle bag offers a practical solution for transport: the 85 cm, 100 cm and 130 cm chain lengths can be stowed safely and compactly in the bag under the saddle.The connecting chains  with the exception of the 150 cm chain  are available either individually or as a set with the matching saddle bag.
