TheDUMMY HUBslides 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 DUMMY HUB is compatible with all multi-speed and 1/8" chain and can be used on frames featuring open dropouts or 12mm thru-axles.
The unique design allows the bicycle to be pedaled and the derailleur to be shifted, making the CYCLINGCORE'S DUMMY HUB an essential tool for chain cleaning or diagnosis of some derailleur issues.
Replaces the rear wheel on a bicycle for cleaning and transport
Works with all derailleur and 1/8" chain
Compatible with quick-release and 12mm thru-axle bike frames
Allows the bike to be shifted with the wheel removed
The DUMMY HUB makes cleaning and transporting bikes much easier. It's designed to keep your chain under tension to enable pedaling forwards or backward and to allow rear derailleur movement with the rear wheel removed. This is useful for a number of reasons.
Also, if you're a stickler for keeping your drivetrain as clean as possible, lubing the chain and leaving it set up on the DUMMY HUB as opposed to the cassette will keep things a bit cleaner.
It's a simple idea beautifully executed and compatible with most current road bikes and many future ones using the 142x12mm standard thru-axle. And it's small enough and light enough to fit in a toolbox or case for a trip.
No, it's probably not at the 'essential' end of the Bike Tool To Buy Next scale, but when you get one you'll wonder why you waited so long.
Makes cleaning and transporting bikes much easier, by allowing shifting and pedaling with the back wheel off!
