ABUSACH Classic Adaptor Chain

The Adaptor Chain Classic is the successor to the proven ACH 2.0 and features a newly designed oval loop ring for easier routing through spokes or tight gaps. Used with a compatible frame lock, it adds a second layer of security by allowing your bike to be secured to fixed objects like bike racks or lamp posts. Simply loop the chain around the object and plug it into the frame lock or Alarmbox 2.0, no extra key required. The same frame lock key secures both components for seamless use. Made from hardened steel with a textile coating, the chain delivers strong protection while safeguarding your bike’s paint.
