High-security anti-theft chain made from special alloy steel. The links have a ‘D’ (or square) cross-section and undergo a case hardening and tempering process that gives them an extremely high surface hardness (57–60 HRC), making them highly resistant to cutting with bolt cutters and hacksaws.

Unlike cheaper chains, this version is coated with a heat-shrink sleeve: after fitting, the chain is placed in an oven at 200°C, causing the plastic (visible in blue) to adhere perfectly to the metal. This process prevents the sleeve from slipping or breaking easily, offering superior protection against both the elements and scratches on rims and chassis.
