The Absolute 9 is a high-quality chain. It is designed for bikes that are parked for long periods of time in a busy area with a high risk of theft (for example, in a city or at a train station). The chain has an ART 2 star rating, which means that it meets the requirements for bicycle insurance. To meet these requirements, the lock has extra thick links of up to 9 mm. This makes the lock heavier, but gives better protection against theft! The Absolute is 110 cm long, making it easy to attach your bike to a pole or fence. The diameter of the hardened steel links is 9 mm and the cylinder has a cover. This means that the cylinder is protected from moisture and dirt so that you can enjoy the chain longer. Furthermore, there is a strong polyester cover around the chain that ensures no scratches on your bike.
