99.99% chance it takes a 68mm english threaded BB.

Calipers are the most accurate, but you can use a ruler that has mm on it. Just measure the frame width where the bottom bracket goes. More than likely, it will be either 68mm (english) or 70mm (italian) - and as the last poster said, it's almost certainly 68mm.

If you measure it and get 69mm, buy a new ruler.

I'm looking at sheldon brown's website for crank sets and it's talking about 107mm and 103mm BBs. But when i look at bottom bracket sizes they are all like you mentioned, 68 or 70mm. What should i be looking for?
