The dimensionally stable Goose Lock chain lock features a unique housing design, soft-touch coating and specially hardened steel. For the good feeling of security and a special feel. With the Goose Lock, ABUS has developed a dimensionally stable bike lock that is also highly appealing to the eye and to the touch and features impressive colouring and design technology. It is made up of several components: the classic 6-millimetre steel chain, the gooseneck, the foam cover and a coating made of plastic fibres. The steel chain – like the housing and structural parts of the locking mechanism – is manufactured from specially hardened steel. The term "gooseneck" refers to two metal spiral springs wound together that ensure the dimensional stability of the lock. This allows the lock to be bent into the desired shape and wrapped tightly around the bicycle frame. The foam ensures the unmistakable feel of the lock and rattle-free transport. Excellent protection against abrasion and scratches is provided by the durable, highly flexible coating made of plastic fibres. Thanks to the dimensional stability and the foam, it is very easy to transport the lock. It does not rattle on the bike frame, yet still remains flexible. It is available in different colours - for an individual colour statement to match any bike. - 6mm chain with functional, durable and highly flexible textile fibre sheathing - The chain, housing and structural parts of the locking mechanism are made of hardened steel - Won't rattle in transport thanks to dimensional stability
