Unless appearance trumps performance, do some real research before investing in "aero" rims. Can you sustain 26 mph or higher running solo for an extended period of time? Only a tiny percentage of cyclists can. If your solo speed is similar to that of 99%+ of cyclists, "aero" wheels will offer no real benefit for you (except the poseur benefit, of course). You've got to be turning higher-than-enthusiast-level speeds before aero rims will have even that tiny 1st place vs. 2nd place benefit they claim. Light wheels benefit everyone. "Aero" wheels are for the already fast (and poseurs).

You will gain more weight AND aero advantage from losing the rest of your weight than you will gain from either set of wheels. The heaviest and least aero component, by far, on a bicycle, is the human body. Keep up the good work!
