Cranks&Spindle -Derailluer Threads

Being pretty much a Campy/Italian bike guy.......hope these aren't silly questions.

Will my Campy cranks swage right onto a Shimano spindle? Pics are below.


Thank you.

Bikes: One brand-less build-up, and a Connondale Synapse Carbon Ultegra Disc. A nicer bike than I need, but it was a good deal, so... ;-)

I believe the answers are "No" and "Yes". I'm being tentative in part because I'm not sure I'm understanding your questions correctly.

I don't think Campy cranks will fit on a Shimano spindle, because the splined types are different splines, and the square taper types are a different taper. However, I'm no expert on Campy.

A Campy REAR derailleur would attach to the bike by the rear deraileur mount, at the rear dropout. This should be no problem. The only part of a bike frame that is "English threaded" (vs Italian threaded) would be the bottom bracket, and I can't imagine how that would affect the rear derailleur.

Thanks...no doubt the BB has zippo to do with the derailleur. I'll have to check on the Campy crank/Shimano spindle interface.

Worse comes to worse, I'll pull the Shimano BB and put in a Campy compatible BB.

That's an Octalink spindle:

You might as well take it out of the bike. It was Shimano-only and only used for a couple years. Shimano's not making them anymore, so you're better installing a Campy BB that matches your crank anyway.
