Campagnolo and Shimano--a new twist?(9 posts)

Campagnolo and Shimano--a new twist?crestlinefarm
May 30, 2003 10:57 AM
I'm converting a mixed Shimano drivetrain for a Campagnolo Mirage STI. Are any of the components compatible? Specifically...
Will a Shimano Ultegra cassette/derailers work with the Campagnolo STI shifter?
Will the Campagnolo crank arms fit a Shimano 105 (square) BB, or will I need an English threaded Campagnolo BB?

I foresee many days of part-swapping in my future...

Was that yes the Campagnolo crank will fit Shimano 105 bb?
Or yes I will need a Campagnolo bb?
Thanks-

Sorry. You will need a Campy BB. Campy and Shimano BB tapers are different.
To be explicitKerry

Campy and Shimano square BB axles have the same taper, but are different diameter. The cranks will fit interchangably, but they will not go the distance onto the axle, possibly affecting the chain line.

The Shimano cassette will work! I just switched a bike over to Campy Veloce from shimano tiagra. I bought a Ultegra cassette so I would not have to buy new wheels after the shop tuned it all up it works perfectly.

As to the drivetrain...

You don't say if it's 8 or 9 speed... but assuming 9

You will need a new Campy R derailer as well as a new set or Ergo brifters. The Campy/Shimano 9 spd. cogsette spacing is very close and you may well get away with the Shimano cogset on the Ergo levers, or you can convert to a Wheels Manufacturing Campy spaced on a Shimano hub cassette ($100 or so).

The Shimano F derailer will work with Ergo though I'm not sure why you are also converting to a Campy crank, as the 105 is a fine crank.

A Shimano rear wheel/cassette can be used with Campy 9-speed rear derailluers.

I suspect I could have been clearer when I said " The Campy/Shimano 9 spd. cogsette spacing is very close and you may well get away with the Shimano cogset on the Ergo levers".

The spacing is off by 1.5mm over the entire range, or so I've read and that's often fine with folks, but is not with others - perhaps more anally retentive like myself (but not enough to spell check). I was OK with my Centaur Ergo on a Shimano 12-21 cassette, but prefer the crisper WM cassette that's Shimano hub compatable but Campy spaced. It DOES shift better.
