I have a 72 gitane grand sport with the original rigida steel serrated rims on it and wanted to find some replacement pre-built wheels for it. Anyone have any tips on which I should look at? I haven't and don't feel like building my own at the moment and just need something lighter and safer than what's on it for light neighborhood riding, nothing fancy. I also am going to make it a 5 spd to simplify thing as well, not sure if that matters. Thanks in advance!
