For a bit of background, I learned to yoyo during the late 90s boom but never progressed beyond some basic tricks like trapeze and brain twister. But over the last several months I’ve been going full-steam, both for learning new tricks and buying a lot of different kinds of yoyos. I’m getting much better, and I usually spend over an hour a day playing with my top dozen or so favorites. Despite that, every now and then a question pops into my head due to my lack of experience. I was hoping that perhaps someone more knowledgeable would be able to answer some of these questions. So, with that out of the way, why is it that some new bearings are quiet from the very first throw, then all of a sudden are noisy from then on?
For example, I recently got another Shooting Star and my first Speedaholic XX. I figured that they’d be pretty close to one another, given that the material, shapes, and specs are all very close (spoiler - they are very close, at least to me). But the Speedaholic XX originally surprised me in that I could barely hear or ‘feel’ the bearing, which gave it a very floaty quality. But then, probably around the 10th throw or so, it completely lost the quietness and now sounds just like the Shooting Star - a bit noisy but nothing that bothers me. This isn’t the first time I’ve run into this, or the first yoyo that this has happened to, so I was wondering what causes it. It’s almost as though some dust got in the bearing, but I doubt that’s the case since I didn’t unscrew the yoyo and the noise started in the first five minutes or so of play. Is this sort of thing common? Have others run into it too? What’s the cause of the noise, is the bearing just getting ‘broken in’?
FWIW, the noise doesn’t bother me and it plays just as well as it did when it was quiet. And while I could put in a tiny bit of thin lube, I’d rather hold off on that as I don’t want to lose any sleep time. I wouldn’t consider it a problem, and I’m not really looking for a fix. I’m just trying to understand what’s happening inside the yoyo that makes it noisy.
Thanks in advance!
