Assembled and worked on a lot of Gitanes BITD.
A few years ago I picked up this shop worn but NOS Interclub frame. I estimate that it was made in the late 60's. The red grease that Gitane used in the headset was still good! The tubing was stamped "SOVEXIA" which I've never heard of.
I got it to build a SS but the frame turned out to be too big for me to safely ride so I swapped for some goodies at a LBS.
