What would you recommend for a woman, 122 pounds, riding just under six hours, on a Trek Team Time Trial frame. She has a set of hed 3’s but certainly does not want to ride the front one in those crosswinds. I was thinking a more shallow spoked rim in the front and keeping the tri-spoke on the rear. Or would you go deep rim rear and shallow up front, i.e. Zipp 303 and 404 combo?
Not having raced at Hawaii, and not even owning a pair of race wheels yet, but reading about the conditions it seems she would be well to do on Hed 3 rear and a shallow front like the 303 or even a Nimble Fly. I believe having more surface area in the rear would actually help with bike handling in those crosswinds. See bicyclesports, J. Cobb wrote an article about it. I think the real question is do you just buy a front 303 or for a little more get the pair.
