LOL on the motorbike!

See the calipers dangling uselessly?

Get the brakes to release so the wheel does that when it's fully assembled and then they'll have something!

I want to convert the ShWing to drums.

Or put drums on it!!!! The back wheels in my Sport Coupe spin like that motorbike wheel- no brake drag and they're running in gear oil. The front wheels on my '59 Bel Air spin like that too; they have ball bearings, drum brakes, and of course are large diameter so the flywheel effect lets 'em go for a loooooong time.

I'd feel better about the bicycle "test" if the rims 'n' tires were identical, and they were spun by electric motor to identical rpms at the start. IMHO adjustment and lube, as well as quality of mfg tolerances could easily have more effect than composition of the balls 'n' races.
