I remember getting ABEC-5 bearings for my blades back in the day. Felt like you were rolling on ice. ABEC-7 was an option, but they were so expensive and the gains were supposedly marginal. Still, I sometimes wonder about what they would’ve been like.

Really no different. The ABEC rating is about machine tolerances so they can spin really fast.
Roller blades and skateboards just don’t go that fast. Also the impacts and crap that they get off the ground damages them far more than what an industrial usage setting would.
They’re just fleecing customers

I had huge 100mm wheels, so I thought I felt the difference between ABEC-3 and -5, but maybe that was just placebo.

To quote Wikipedia:
ABEC only rates tolerances. Nothing else. They were rated bearings you had so they performed better than chinese knockoffs. If you wanted good stuff, go with Japanese, German or Korean.

I could be wrong and really don’t have the math in me, but I believer we’re taking about thousands of RPM here

Was big into roller skating as a kid. Had ABEC-7 bearings in my skates. They rolled extremely smooth for the first month or so…then they were normal skates again.

You didn’t clean them weekly?
Man I did, but they were hockey skates (ice was not a thing here at the time) and I wanted to get every ounce of performance out of them.
Cleaning bearings, rotating wheels, relacing them cause my feet grew crazy for a while.
I was a weird kid though. Now I’m just a weird adult.
