Thanks RustyUs!
That is great information and Bearing Manufacturers for me to research. The reason I asked here was based on an Adam Drake bearing cleaning video I saw. He was cleaning NMB bearings and it sparked my interest what type of bearings I had. At the end of the video, he spun the wheels of his Mugen and the whole drivetrain spun for like 20 seconds, more or less. (But it seemed like an eternity to me!!) My build, which has only 3 runs on it on pavement, spin maybe 4 to 6 seconds. It could be a LARGE number of things why my drivetrain doesn't spin like his, but at least I would be able to eliminate the bearings from the equation.
