More and more people are beginning to realise how important aerodynamics are on a road bike, more so than weight . This article really puts it into perspective.

Keep in mind, though, that solo requirements are not the same as pack riding.

There are some pretty light aero wheels and bikes around now, too -- the best of both worlds. A fully aero Cervelo P3, with 60 mm front and disc rear Zipps is only about 18 pounds.

"More and more people are beginning to realize how important aerodynamics are on a road bike, more so than weight ." I think the truth is, people are trying to figure out at what point aero and lightweight equipment has the advantage in hilly TT's.
I think we hear a lot more talk about weight than aerodynamics because for most racers, TTing is a pretty small portion of their total racing and most use different equipment for each of them. With most amateur racers focusing on road races and crits, a lighter bike is of more value, when most of the aero gear is illegal or of little use in a pack. Most racers I know, go fully aero for TT and try and reduce weight for hilly RR which makes sense. If a guy shows up to a RR with aero wheels, he is a marked man. The pack will make sure that they keep an eye on the guy who may TT off the front! I think the biggest question is "Is the course hilly enough to have an advantage on the lighter bike,". That is what the calculator is good for.

I've been debating on whether to use my road bike with "Spinaci" type clip-ons and Zipp 303s or my Cervelo P2K with a Zipp disc for a 2.8 mile TT prologue in the Estes Cycling Challenge Stage Race. It's an uphill TT with only a 3% grade so it sounds like the TT bike will be faster. Before reading the article I was leaning the other way.

I guess no one bothered to check these out when I posted links to that forum.

execellent! i've thought that aero was not that important unless you are doing a time trial or breaking away in a solo bid for the win. if your the third man back in a pace line how much aero benefit do you really get from your 40mm rims? if your out on a training ride what difference does it make how fast you go but how hard you go that makes you better.(i know some times you go slow to recover). i think that we get caught up some times in the latest gadget or accessory(sp) and the manufactors(sp) try to add on things much like the auto industry with special equipment packages. one last thought if you have the extra bucks by all means spend it on what you want.

I think the point of article mentioned in the original post is "what is significant"? Even with all that analysis, it seemed like all the aero stuff there only made about a 20 second difference, but in that race it was the difference between winning or not.

In pack racing, especially with hills, everything is different. I doubt many people would disagree with that.

For training alone, you are right, it doesn't matter at all. For training with others who may be faster than you, it might matter, if staying with the group is important.

For those of us who are'nt pro racers, I think there are other factors to consider i.e. climbing ability of the rider, and comfort on the bike. For example, I am preparing for a 10 mile TT on a rolling course. I took both my road bike and my TT bike to the course to compare. My road bike, which I ride everyday, is a Calfee Tetra Pro with Ksyrium SSC's. My TT bike,which I only ride in trainig for TT's, is a Calfee Tetra Tri with full TT setup. I rode the course nearly two minutes faster on my road bike. My theory as to why is that ,as a big guy (205 lbs), I was able to climb faster with the lighter wheelset. I also was not comfortable in aero bars at 40+ on the downhills. So in my particular case, I'm going with the road bike. Just my $.02.
