Bearing size for a Quando hub

I Tried to service a rear Quando hub today. Went to reinstall the bearing and realized they are two different sizes, nine 1/4" and ten 7/32" balls. Two different size bearings in the same hub is crazy, right? Nine 1/4" balls is really tight fit leaving no gap. So, it's either eight 1/4", or ten 7/32".
Any Idea, thanks.

I once had a quando hub and used 1/4". Maybe i only measured one side and assumed both are the same?
they are crappy haubs anyway, so just use what works.

BTW, i had to replace a cone and of course couldn't find one, LBS was no help. i just measured what was needed and got a cone from Wheelsmfg. Overall wasn't worth it the cost.

Lots of Quandos here. Not nearly as bad as they are cheap.

99% of the front ones use 4,762 mm (3/16″) 2 times 10 at each side, while 99% of the rear ones use 6,35 mm (1/4″) 2 times 9.
Setting preload perfectly is a bit trickier than with Shimano - some just can't be adjusted to turn smoothly, but without play. Go for the preload that just eliminates play and they'll work fine and last pretty long.
7/32 for a rear hub is strange.

After playing with some more, I'm convinced it was made to use two different size bearings. Nine 1/4" balls will fit in the non-drive side, but not on the freehub side. The 7/32" don't work at all on non-drive side. The cones are a different diameter. It feels smooth as any mid-line Shimano hub I've ever worked on, but what an odd set up.

I have seen this before as well, when a customer came into the shop with their fixed gear wheel, it was a Quando branded rear, fixed/free flip-flop hub. From factory it had 10 x 7/332" bearings on either side. Luckily for us, we didn't make any assumptions and measured.
