So, I have a Duncan Speed Beetle, which is a nice, inexpensive starter yo-yo. I’m looking at the bearing however, and there’s no way to get into it to lube it up. It almost seems intentionally designed such that once the lube in the bearing wears off, it’ll stop being responsive and there’s a shield over the bearing race that appears to be good for not much more than preventing the owner from adding lubricant.
To add to the issue is the fact that Duncan appears to attempt to keep players in the dark by assigning letters to their bearing sizes, rather than listing the sizes.
So I might be looking to replace this bearing. Duncan says it’s a size A bearing.
I believe that means it measures 5mm x 10mm x 4mm. I’d like to look into getting a new bearing (one that doesn’t have a shield, so I can lube it).
Am I right that the dimensions of this bearing are 5x10x4?
Am I also right that Duncan seems to have done this on purpose to both force a player to replace the bearing (by not being able to lube it), as well as obfuscating the dimensions so that you have to buy it through them?
