Dummy Hub

The DH-1 Dummy Hub slides into the rear dropouts of a bicycle frame and replaces the rear wheel, keeping the chain in place while the wheel is removed for cleaning, service, or transportation. The unique design allows the bicycle to be pedaled and the derailleur to be shifted, making the DH-1 an essential tool for chain cleaning or diagnosis of drivetrain issues.
