I recently acquired an older blue Motobecane Mirage with a great frame and paint. I have stripped it all down and salvaged everything I can (frame, front wheel, handlebars, front brake) but now I'm left with a quandary. What type of bottom bracket/crankset/rear wheel will I need? There is something bizarre about the bike so I've read but I can't find a solid answer. -Aaron
Having converted 2 70-something Motobecans, take to your best local shop to figure out what fits your bottom bracket. As Mikes asked French? Reverse threads? As a last resort, Velo Orange has a bracket that will work. DO get rid go the cottered cranks!
