ABUS ADAPTOR CHAIN Classic 5.5KS/130 black – Flexible Additional Security for Bikes & E-Bikes
The ABUS ADAPTOR CHAIN Classic 5.5KS/130 black is the ideal upgrade for a compatible frame lock or the Alarmbox 2.0. This plug-in chain has been designed to help protect bicycles and e-bikes not only from being rolled away, but also from being carried off.
Double protection for everyday security
While a frame lock secures the rear wheel, the ADAPTOR CHAIN Classic allows you to attach your bike to fixed objects such as bike racks, lamp posts or fences. Simply wrap the chain around the object and insert it directly into the lock body. A key advantage: no additional key is needed, because the frame lock key locks and unlocks both components.
Optimised design for easier handling
As the successor to the proven ACH 2.0, the ADAPTOR CHAIN Classic features a newly designed oval loop ring. Its slimmer shape makes it easier to guide through spokes and narrow gaps, providing more convenient handling in daily use.
Strong, durable and paint-friendly
The 5.5 mm square chain made of hardened steel delivers a solid level of protection for everyday bike security. At the same time, the textile coating helps protect the frame from scratches and paint damage, making it especially suitable for premium bicycles and e-bikes.
130 cm length for greater flexibility
With a length of 130 cm, this plug-in chain offers extra flexibility when securing your bike to larger or less accessible objects. This makes it an excellent choice for everyday city use, commuting and longer rides.
Convenient transport solution
For transport, the chain is compatible with the ABUS ST 5950 2.0 saddle bag. It can also be carried in the ABUS ST 5050 saddle bag. Both bags are mounted neatly under the saddle, providing a compact and practical storage solution on the go.
