Thanks! I think I already am getting a little addicted. I was at a bike shop recently and I saw an old Schwinn road bike with downtube shifters and a bent wheel. I was interested, but the owner said it was junk and moved me along. Maybe I should see if they still have it.
I just cleaned the drive side bearing and I was almost leaning towards re-using it, most of the balls looked pretty good, but then I found one with a really deep gouge several millimeters long! I'm not sure how that could have happened.
This looks like it should work:
1/4 9-Ball Sugino/Tange Retainer
The crank is a Sugino VP, the balls are 1/4" according to my digital calipers, and the bearing looks exactly like that.
About the saddle: it came with the gel pad. I normally don't like a cushy saddle. It's dark green under the gel pad. I didn't like the saddle being the only dark green thing on the whole bike, but now that I have Velo Orange dark green cables that may actually match I'll see how it looks.
