I remember doing the calculations a few years back.
Fastest a skater goes on a long board is about.....110kmh.....ishhhh
Like max +\- 5000 rpms
Imagine the speed you’d have to go to get to 20 000 rpm rated bearings made for industrial machines,
Completely agree. I've seen the math done a few times over the years along the same lines - always with the exact same result.
Even the durability thing is just publicity. Get some 20$ reds, go skate and buy a cold one instead. Even some pros ride mini logos.
Zealous are $14
