Okay, so I continue to hear the advantages of deeper dish rims. How they can have better rolling resistance, better aero, etc. But, wouldn’t this depend on course conditions ie. wind direction, intensity, amount of hills, etc. For example, say you have a bike course that runs north/south with the course conditions forecasted to have east/west winds of 10-15kts. If you had deeper dish rims wouldn’t this provide more of a surface for the wind to hit (slowing you down or at least causing you to fight the bike more). I’m always hearing about what upgrades one should put on their bike, but I don’t think it’s cut and dry regarding wheels or is it?
The best thing you can put on your bike is less of you.
At 168 and dropping, I’m working on it.

play with that for a while

Good site. I’ve sort of wondered whether these manufacturers are using different angles, because you always see these guys in the tunnel getting blasted head on. I don’t think I’ve ever seen them testing with a cross wind component.
That greater surface area that’s exposed to cross winds doesn’t slow you down in the forward direction of travel, just pushes the bike sideways (which you correct for of course).

Actually…the “sideways” force is resisted by your tires on the ground.

zipp’s website has PDFs showing yaw angle testing as well.
zipp and hed use the curve of their wheel shapes to tune what yaw angles they perform best at
and, surprisingly, discs just get better and better the more crosswind there is (usually) =)
Oh, they do, and have since at least 2001. That was my last trip to the tunnel.
the best wheels for you are the ones you can make round and round the fastest…ride more!
