Tire and Wheel Comparison

With our new Michelin order going out soon, I thought it would be a good idea to look at some date regarding tire/tube combinations and wheel weight vs. aerodynamics data. Chris Burnham supplied me with the articles here. In this first review article, it appears that in comparing clincher tires/latex tubes to tubular tires, the clincher tire/latex tube combination seems to have comparable to superior rolling resistance charachteristics vs. tubulars. I know Lance is going to say that tubeless tires have the least rolling resistance, and that's probably true, but tubeless wheelsets still haven't taken the industry by storm... yet...
Think your lightweight climbing wheels are better on climbs vs. an aero wheelset? Maybe not... Here's some data that suggests that on inclines of less than 8% grade, you're still faster on an aero wheelset vs. a lightweight climbing wheelset. Finally, I've also got an article comparing the aerodynamic drag of various wheelsets. Yes, Zipp wheels are faster than Mavic R-Sys.... I know we already know that, but it's nice to see it in a graphical comparison.
What's this mean? Since we're doing a new Michelin order soon, you may want to think about ordering some latex tubes if you're interested in achieving low rolling resistance. I've been using them since our last order, and aside from having to pump up my tires more often, (latex doesn't hold air as long as butyl), they've been working out great. I haven't had a flat tire on them yet, and they're a lot easier to install than the tubular alternative. One disadvantage is their price. They will run more than double the price of the regular tubes, but hey, we're getting a team discount, so it's not that expensive, and it's still less than purchasing tubular tires. Also, the other data suggest that you could probably use your aero wheelset on a fairly hilly course and still get an advantage over lightweight wheels. Reserve your lightweight climbing wheels for those races that exceed 8%, or have a lot of cross wind.
