I have a 89 3.0 cannondale that currently has a shimano 105 52/42 double. I am now living in Italy and riding Mountains and need a lower gear. I am going to buy a triple crank 52/42/30, probably a stronglight or similar (something that won't break the bank). I know I'll need a new BB, but not sure which one. obviously english 68mm, but what about width?? How do you determine which width you need?

The width (as well as type) is determined by your crankset. - TF
