I wonder how many Cinelli bivalent wheels EVER got changed in a race such that the orientation mattered!
For starters you needed a pair of them, some sort of mechanical failure and a third wheel!
Anyone know of an actual example of a Cinelli wheel changout in a race?
Where it mattered?
Don't get me wrong- these are neat, but very theoretical, parts.
All that said I wish I had a pair!
