Thanks for the input. It looks like the BB in the Cannondale is held in with a metal ring with splines on it. That suggests to me that a tool with splines will be needed to unscrew the ring and then another tool will be needed to install the new BB.

I'm guessing this to removed old from Cannondale:

This to install new Shimano and MegaExo

Chris_W also mentioned something that my LBS guy thought might be a problem. Until I go 10 speed, I might get some chain run in certain gear combinations. Does that seem likely? LBS guy thought I might need to get new chainrings if I do the crank but stay with the 8 speed rear.

Thanks again for the benefit of your knowledge.

Oh, one more question: I think the Bianchi uses english threaded BB correct?
