Tnx tester. I wonder why wheels don't come with a drag coefficient. It's not hard to calculate. Put them on a work bench at a constant temperature, rotate them at a given speed and see when they stop.
Don't know if @danstuff is saying the same thing, but wouldn't that just measure the friction of the bearings not the wind resistance?
I guess both, and both are important. Even if not 100% reliable would still give a good idea?
