It sounds like you want to use a Stronglight BB spindle with Campy Italian cups in a 70mm wide BB shell???

Campagnolo and many other brands used 68mm spindles for French and British BBs, 70mm spindles for Italian BBs.

Stronglight and TA used 68mm spindles for all three standards. The Italian cups were 1mm thicker on each side to fit 70mm BBs.


118mm was the standard width axle for Stronglight doubles with 120mm used on some bikes.

It may work but the adjustable cup may go in 2mm too deep leaving insufficient threads for the lockring.

Other problems: the holes in the Campy cups may be too small to clear the end diameters on the Stronglight spindle or too big letting gunk get into the bearings.

Also, the ball tracks may be in different locations between Campy and Stronglight spindles giving improper ball contact angles.



Proper contact angle



Stronglight Italian cups regularly come up on eBay and they are usually not too expensive. There is currently a NOS set for $69.99 but I've seen them for a lot less money. TA cups interchange with Stronglight.

Do you have a Campy spindle and have you tried sliding the 49d arms on?

I did this Flickr album in a hurry back in 2011 but scroll through the pictures and it shows workable and non-workable combination fits. Check my comments below the photos.
