Information:

With slightly smaller, squared links compared to the BEAST chains, the MASTIFF series offers bicycle owners and powersport enthusiasts ultimate security for use in high crime areas. Oversized, titanium-reinforced hexagonal links render hacksaws and bolt cutters virtually useless, while tight inside link dimensions make prying impossible. Available in a wide variety of chain lengths and link sizes to match your security needs.
