Ok, assuming this is serious,and you really are going to spend $5000 on wheels, and you're not very heavy,here's the arsenal for all your needs. Zipp 404's for all around racing ,and tris were its too windy for a disc. HED disc,and A HeD trispoke for traithlons,and TT's. Zipp 202's (hence the wieght comment ) for hilly road races. For $4000 bucks you will have the wheel for every occassion.
