Bearing sizes
Easy question from a noobie:
What would be the most common bearing sizes? (hubs, pedals, headset, BB)
I'm working mostly with vintage bikes, and will be looking for a bearing supplier to order a batch for overhauling.

5/32, 3/16 and 1/4 are the most common. Campagnolo front hubs are unique and use 7/32 and some one piece cranks use 5/16"
Also for your purposes buy grade 100, or 300. If you find yourself working on high end bikes you might want to spring for grade 25.

Thanks for the help.
If I can't find a supplier I'll order some from that auction site.

Search bearing balls, not ball bearings, and you'll find a number of sources, then it's a question of minimum orders.

Wow - that *is* cheap! I wonder what grade they are - I'm guessing 300 or 1000 if they're anything like the ones LBSes sell on cards.
