I've been testing some different wheels to buy to replace my FSA tubies that have been breaking spokes too frequently. I was torn to get a set of new tubies but I wanted to play around with different tire sizes and clincher was the only way to do that so for the most part I check out different clincher wheelsets. No science behind my testing but more of a feel on how they felt.
The FSA tubies are light and didn't feel pushed around in the wind but were not easy to relace. Together with my bike the overall weight was only 14.12 lbs!
The Shimano Dura-Ace C50 tubies felt great and were fast and light but I wanted to go with clinchers so they didn't make the cut. They felt like they were effected by the wind more than the others also.
The Enve SES 6.7 were the deepest that I tested but felt like the fastest that I tried; I could feel them in windy conditions in a negative way when it got in the 17+mph windy days. I had also tried the SES 3.4s; they were great but I didn't feel that they were as noticeable as the 6.7s The 5 year warranty, the choice of three different hubs and being made in America were big pluses for them. Oh, thanks for my buddy Beck helping to model the Enves in this picture!
The Zipp 404s have always been my favourites; they felt fast and didn't seem to get blown around for the depth. A great wheel set and a close 2nd only to the Enves.
I ended up going with the SES 6.7s, Chris King ceramic hubs....the weight difference between the 3.4s and 6.7s were only around 120 grams but the "perceived difference" in overall speed of the 6.7s and the way they felt made them my choice.
