Bottom Brackets

Can someone let me know how I find out what size bottom Bracket I need? I see they all come in different sizes so as not to buy the wrong one I'd need to find the size.
A measurement across the shell will confirm it as a 68mm.
Remove your cranks and measure the length of the axle from flat to flat (x).

Your BB is a 68 x (x), like a 68 x 113 for example.

Thats all you need, its not rocket science.;)
