I just sold my UO-8 conversion i did last year a couple days ago. The cottered cranks were a pain to remove. I had to use an italian spindle and put on a set of SINZ cranks. I found an old single speed wheelset from a Redline I put on. Be careful when switching to 700c wheels cause dropping the brakes makes them lose their effectiveness. The fork I had to pry apart a bit to fit the front wheel in....not much....just a little tight. It was a great ride, just a bit too big for me at 63cm.
