  1. This is basically an 808 vs 404 question. I'm researching new wheels for road racing and need all the help I can get, so I figure deeper is better regarding Zipp wheels.

    I'm sure this has been gone over before, but I'm after information specific to the Zipp wheels, as I understand their profile is such that deeper rims aren't necessarily that much of a handful in breezes.

    I have other wheels I can use if there is too much wind, but for your average inland day at the races with maybe a slight wind would the 808 offer more than it takes in terms of aerodynamics?

    I saw in the roues artisanales website that the 808 only offers 3 watts lower drag than the 404, so I'm wondering if the risk of wind-related handling issues is greater than the marginal aero saving.

    Since most of the racing is on flat or rolling terrain weigh isn't an issue. I'm wondering if deeper wheels - which seem to be gaining popularity in the pro bunches - really can offer me tangible benefits over what is now the standard 404 depth.

    I assume that would be 3 watts directly into the wind. I'd like to see how they'd measure up in a light cross wind. Heck, I'd like to see how they'd handle in a light cross wind. Consider an 808 in the rear and a 404 in front, just to keep from getting blown around.
