I upgraded my Mavic Aksiums a few years back with a set of custom wheels. It's a pretty basic build: Velocity Aerohead rims with White Industries hubs. Sapim double butted spokes; 24 (I think) in the rear and 20 in the front. I love them, and my husband has a similar set. We both love them. I shied away from prebuilt wheels because many are overbuilt for someone my size. I also didn't want bladed spokes. I think you can often get more bang for your buck with handbuilts.

Ron Ruff at White Mountain Wheels built my husbands wheels. If I were in the market again, I'd call him or another reputable builder. Tell him what kind of riding I do on what kind of roads and let him recommend a build within my budget and weight.
