I don't know if you noticed but the whole darn bike world seems awash with BB sizes, you've got your different length spindles for mtbikes, your three different 'euro' shells (two widths and a threading annomaly from italy just to mess things up) Cannondale has been putting out what they call their 'system integration' or SI setup which uses a completly different everything short of chainring mounts and pedal boss, Pinnarello is doing something practically the same only, different. Then of course there's truvativ with their oversized version of the isis/euro idea. And we haven't got into the ****storm in bmx. What you haven't heard? there are now four differnt shell designs competing for supremacy over the now effectively passe euro and american.
So what do you do? What if you want to make an intergrated system?
