Hello,

I'm looking to replace the bearings on a friend's bike. I've never done it before but of course that's why I volunteered to do it. I've read online in several places that "most" rear hubs have 9 1/4" bearings on each side so I was just about to order some 1/4" bearings when I thought "maybe I should have a look." Well, inside I found only 7 bearings on both sides which makes me wonder if they might also be a different size.

The only identifying mark I can find on the hub says:

K T
ROCTAIWAN

It's from a 70's World Traveler (schwinn import) and I don't know if the wheels are original but they are straight and look pretty nice on the bike so I feel like it's worthwhile.

Thanks!
