Heres what I did. This Gitane was pretty bad when I started. Pulled the cottered crank and put on a Sugino crank, and used the original Gitane BB cups. Suntour Gt and Sprint Derailleurs had already been put on by previous owner. The Suntours work way better than the Simplexes. I also painted the bike with a brush and worked around the decals. Two coats of Gloss enamel matched to the original color.
