With oversized, anodized aluminum tubes, a wide and stable base, stronger jaws, and faster closure, the Pro Mechanic HD matches the expanded capability of today’s bicycles. It can support bikes up to 100 pounds (45.5kg) and tube diameters to 2.6 inches (6.6cm). Yet it’s lightweight and portable at 18 pounds (8kg) and 8”x43” (21cmx115cm) when folded for travel.
