campagnolo bottom bracket question

Have you seen this? If I've done my sums correctly, then "old style" BB were 111mm and "new style" 113.5mm.

I wonder if the VB contributor confused the marking on the axle: "120" refers to the rear spacing and not the BB.

The Shimano BB you were using would equate to 119mm ISO: what was the gap twixt ring and stay like?

yes i agree with your calculations too.
