You
are good, but I see I have to spruce up my language a bit in this particular forum. I have spent too much time in the
Tour de France forum lately.
Of course you are right - it is the number of shifts. And the quality of same probably. But they are extremely accomplished riders who switched to "modern" Campa from Nuovo Record, so who knows.
And there
are three different level Ergos and two different riders involved so I would hope the quality issue was not it. They ride almost always on flat terrain in the DC Metro area, so I would also hope that the number of shifts was not more than I need in the rolling foothills of the French Alps, where I have encountered no such problems with two riders and three sets of Ergos of two levels - 9s and 10s.
