Bordo Granit X-Plus 6500

ABUS, founded in 1924 in Volmarstein, Germany, has been making bicycle locks since 1931 and is the dominant European brand in the category. The Bordo line, launched in 2007, was ABUS's most important bicycle-lock innovation in decades: a folding lock built from hardened steel bars connected by riveted joints, which folded compactly like a carpenter's rule and slipped into a frame holster. The Bordo solved the long-standing trade-off between U-locks (very secure but rigid and awkward to carry) and chains (flexible but heavy), and competitors have spent the years since catching up. The Granit X-Plus 6500 is the flagship of the Bordo family — the highest-rated folding lock ABUS makes, scoring 15 out of 15 on their internal security scale. It uses 5.5 mm hardened-steel bars, an X-Plus key cylinder with strong pick-resistance, and a special hardened rivet construction at the joints (historically the weak point of any folding lock). It is rated Sold Secure Gold in the UK — one notch below Diamond, which is generally reserved for the largest U-locks and heavy chains. At ~1.6 kg in the 85 cm length, it is a realistic everyday lock for higher-value bikes used in medium- to high-theft urban environments.
