The wind just pushes the bike sideways, causing you to lean a bit. Bear in mind that I weigh 193#. The crit was pretty much a worst case scenario. The course was a rough rectangle, but turns 1 and 2 were taken almost like one big turn and were downhill. As you hit turn two you came out of tree protection, and were into the wind at the end of the turn, crosswind during it. You also came out of a dip while you were crosswise to the wind. Your front end was light from the dip, and you were just starting uphill as you were hit suddenly with a crosswind of over 30 mph (no exaggeration). Having avoided the crash there in lap 2, I came around on one of the other laps, was hit by a gust at exactly the wrong time, and it blew me sideways enough to almost take me into the haybales. In hindsight, I should have used my training wheel on the front. However, in hindsight, I'd still choose the Zipps in anything up to maybe 20mph.

One other note is that I find the Zipps tend to seek their own path into the wind, and I believe it is the air unattaching and reattaching to the aero shape, sort of like a sail starting to "luff" or a wing starting to stall. My line is more precise with my training wheels. I should tell everyone that before a race, so they don't ride my wheel. ;-)
