I found the info at the Sheldon Brown website
Unfortunately, I never saw the original rear wheel-- I got the frame in a swap and then later got the wheel in a different swap.
Yes, the frame is meant for fat knobby tires, but this bike is for urban commuting, which is why I like the narrower, high pressure tires.
I found ALL the info I needed at the Sheldon Brown website! It is so great and I recommend it for everybody who does maintenance themselves. Just google "Sheldon Brown"
