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, as well as preventing the chain from causing damage to the bicycle. IvyTex technology has many other benefits aside from its durability. The hi-tech fabric is also highly flexible as well as 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. - 7mm 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
