Dummy Hub

Commonly known as a Dummy Hub, the Park Tool DH-1 Dummy Hub slides into the rear dropouts and replaces the rear wheel, so you can easily clean your chain and transport your bike with your rear derailleur and chain secured in place. It's compatible with all rear derailleurs and 1/8-inch chains, as well as working with both open dropout and 12-millimeter thru-axle frames.

Don't be a dummy, use one

Familiarity:: I've put it through the wringer
Weight:: null

Makes cleaning and maintenance on QR and 12mm Thru-axles so much easier. These also come in hand when traveling if you have to remove the rear wheels and don't wan't your chain slapping around, greasing up the place.
