yea, I got mixed up - I think you use 6001 bearings, but for some reason I assumed they have the same OD as 6000 size bearings which are 26mm od 10mm id 8mm width

OK, below are links to the products I’m talking about. They mention increased speed, top speed, etc. Are you sure you are interpreting that formula you posted correctly.

Yes.
Given that the claims of higher speed and lower rolling friction are directly aimed at selling you a product, are you sure it’s not just marketing wank? I don’t see any studies, formulas or empirical measurements to back up those claims.

Again, I don’t think the difference between 608 7-ball and 608 6-ball bearings (even if that one ball does have a significant effect, which I am still not 100% convinced of) really matters at all in the world of powered vehicles. You’re just not gonna feel the difference, because you’re not pushing.
The higher speed also doesn’t matter, because the limiting speed for a 7-ball 608 is 20,000 RPM, which equates to about 250 miles per hour with 107mm wheels. So what if the 6-ball bearings have an even higher limit? It’s not like we’re even close to the 7-ball limit.

Rolling resistance generally decreases with the radius. I think you threw that web page out without understanding it. It’s one of the first websites to come up when you search " bearings" and “rolling resistance”. I think there are a lot of things in esk8 that are just part of the general skateboarding legacy that could be improved upon.

Thanks for your input!
