The current state of affairs with skateboard bearings is a fucking joke. Everybody is screaming “my bearings are da best” or “bones reds for life” or some stupid shit. Its completely unscientific and is an embarassment to humanity that nobody has gathered up every bearing and done a test. The only thing u see are free spinning tests where ppl turn the board upside down and spin the bearing with their hand and time how long it spins—which is pointless bc not all testers spin the wheel the same speed, heavier wheels will spin longer, and the friction when the bearing has no weight pressing on it can be very different from the friction with weight pressing on it.
it would be pretty simple to set up an experiment with a treadmill and a precision newton meter spring scale a skateboard, and a 100 pound dumbbell.
its ridiculous this hasnt been done yet.
