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

Can you be a bit more clear about what you mean by "something bizarre"? And are you wanting to build it up with gears, single-speed, or fixed? –  jimirings Sep 25 '13 at 2:35

Take it to a bike shop. Fixing bike problems over the internet is hard enough, and this question is way too sparse on details. –  joelmdev Sep 25 '13 at 4:05

What exactly are you converting? What do you mean by 'older'? –  WTHarper Sep 25 '13 at 5:11
    
@WTHarper I could imagine he means that it's a French motobecane rather than the new US brand which are produced in Taiwan –  dieKleene Sep 25 '13 at 21:30
    
Is the issue the French bottom bracket? –  mikes Sep 25 '13 at 22:02

1 Answer 1

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!
