Measure your old one, if you are just replacing it, you need one that's the same length in mm, so when you get that number, just make sure to order the same size, and shape (most likely square taper or isis, or octalink, so you may want to post what type of cranks you're using). if your old bb just has square ends, then it's a square taper, and you should be fine ordering that.
