Whats the deal: Bearings

[Marvin]

I don't know absolutely loads about the ABEC scale, but it could be that it's like Michelin Stars for restaurants. 1 star doesn't mean that it's bad, it means that its better than most other restaurants. Maybe this is similar, most normal bearings wouldn't get a rating of ABEC1 so those that do are actually better.

I don't know really, that would be my best guess.
