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.

A Material That Offers Resistance The concept that the IvyTex technology is based on has already been in use for several years in industrial applications in areas subjected to high wear, where moving parts have to be protected against wear and tear. ABUS has taken advantage of this concept by using it in the sleeves for its chain locks. The effect of this is twofold: it provides protection against wear and tear, and it prevents the chain from causing damage to the bicycle. IvyTex technology has many other benefits aside from its durability. The hi-tech fabric is highly flexible, weatherproof, and resistant to liquids. This prevents water from being absorbed by the fabric, thereby protecting the locks against corrosion. Its durability also means that there's no excuse for not securing your bicycle, even if the weather is bad and you worry about the lock getting dirty. - 6mm square chain with functional, long-lasting, and highly-flexible mesh sleeve to prevent damage to the bicycle's paint - The sleeve offers very high protection against abrasion and does not absorb any liquids, e.g. water or oil - The chain, the case, and supporting elements of the locking mechanism are made of specially hardened steel
