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!
