Converting 1980's to Single Speed

[Jordyne]

Hi all!

I want to convert my 1980's Fuji Gran Tourer SE to a single speed simply because it is SOOO dang heavy, I almost roll backwards. I've been doing a lot of reading, but I'm still pretty clueless about the exact details. I know I want to put on lighter wheels (first!) before even doing the single speed conversion.

That said, can you look at the pictures and tell me what measurements of crankarms, etc that I will need? I can't afford to have a LBS do this because I'm broke as broke gets.

Also- if you have any parts that I need, I'll buy them from you!
