What's your BB length? The important measurements are to do with crankset/BB and hub. If you want to keep the cranks then get a slightly longer BB, if not then measure the chainline of your hub and get a crankset/BB to match.
Sorry, to clarify I'll likely be getting new BB as well as crankset as the BB i have is very specific to the current cranks.
