How do I know what size Bottom Bracket to buy for my bike(Fixie)?

I plan to buy a new crankset for my fixie.

and the crankset could fit 103mm-107mm bottom bracket.

Im going to go buy shop and they can help me.

I just want to learn how do I know what size?

I know you have to look at your frame because different bikes have different stuff.

    Remove the bottom bracket, the size will be printed on the cartridge. You can always take the bottom bracket to the shop and get a match.

    Lots of things to read about French bikes at the link. Also, where to buy the parts you need. Visiting your LBS is also a good idea, those bottom brackets are getting rare to find but mechanics may have saved some.
