The plug-in chain from Abus makes double securing your soci.bike against bicycle theft very easy. Place the plug-in chain around a fixed object, pull the chain end with the clasp through the ring on the chain and insert it into the lock housing of the soci.bike ring lock. You do not need an extra key and the chain does not require a separate lock.
The hardened steel plug-in chain is the ideal second protection for your bicycle. With a length of 100 cm you have enough space to find a suitable fixed object.
