I just got two bikes an early 90s Cannondale, and an old motobecane. I have not decided witch one I want to convert yet I was most likely going to put a flip-flop hub on it. Is it best to get shorter bolts for the chainring to convert the crank; what do I do if the sprocket and chain ring don’t line up? The moto has horizontal dropouts but the Cannondale does not how do I go about converting this (with out buy some $150 hub?) [White Industries]

Thanks for the help guys I can’t wait to get this bike going.

Ps I just got my new Kona Unit and it is awesome!
