I currently have ultegra hollowtechs on my bike and I think the bb is on it's way out.
I have a brand new hollowtech bb here but it's mtb not road.
As far as I'm aware the only difference in the systems is that the axle is longer on the mtb cranks and to accomodate this the tube spacer in the centre of the mtb bb is longer and it comes with spacers. So I'm thinking I can take the tube spacer from my road bb and use it with the bearings and cups etc from this mtb one, anyone see any problems with this? The bearing cup parts look pretty much the same as the road ones but I guess they might not be.
