The plug-in chain is your additional security solution for your frame lock or the ABUS Alarmbox 2.0. This allows you to flexibly connect your bike to different objects. The adaptor Chain Classic is a versatile plug-in chain designed to enhance bike security by connecting to a compatible frame lock or Alarmbox 2.0. Its newly designed oval loop ring makes it easier to thread through spokes or tight spaces, while the hardened steel construction and textile coating offer durability and paint protection. With no need for an extra key, the frame lock key operates both components, providing a convenient and doubly secure solution for locking your bike to fixed objects.
