Technical information: Case-hardened steel is heat-treated to harden the surface. This enables it to retain its core elasticity as well as resist surface stresses such as abrasion. Passivated steel has undergone chemical surface treatment to prevent oxidation. The sleeve protects the bike, for example its rim, from rubbing against the anti-theft device, and therefore from scratches.
