I don't know if this is normal or not, but here's the story
I got an old bike to fix up and turn into a commuter fixed gear/single speed with a flip flop hub. I didn't know vertical dropouts were a bad idea before, but I'll deal with that when I get to it.
Anyways, so this bike used 36 hole 27 1 1/4 wheels. I couldn't find a flip flop hub that I could use for it, so I opted to just upgrade to some more modern 700x23cs and sell my wheels. I picked them up yesterday, and it was all good.
I didn't think to check while I was buying it, but a little while after I got home I checked if the freewheel and fixed gears were 3/32 or 1/8.
Well... The singlespeed cog is 3/32. But the fixed gear is 1/8. Is that normal?
