Hi There -

Just the the title says, does anyone know if the Campagnolo BB cups will will with say a Dura Ace crank?

I know they use the same tool, are the bearings the same inner diameter? I think it would be a neat way to keep a little more Campy on my bike.

Cheers

Dave

The Campy cups are just cups, nothing in them. The bearing cartridges are pressed onto the crank spindle halves and the side load is set by a wave washer. Shimano cups contain the bearing cartridges and the side load is set by an adjustment bolt. They are very different and the installation wrench is all they have in common.

That's a pretty final answer to me.
