If anyone can provide any upto date info I would be greatly apprecitive.
I have read that aero posts are actually less aero than round wich is the opposite that I have read numerous times & counterintuitive?
Along the same lines, I recently heard that 700 X 23 have less rolling resistance than 700 X 20, again also contrary to traditional wisdom. I know that for speed, aerodynamics & weight also are important.
Can someone please substanciate or add to these issues?
Thanks very much in advance!

Unless your a Pro, Cat1 or Cat2 I would say Aero accessories or more of a fashion statement (decorative), nonessential but useful. Like Dura Ace or Record, our bikes dont need it, we just want it. Before it can be of any help you have to know how to use it and when to use it. A deep dish wheel set in high cross winds, how much do you gain and how much do you loose? Aero helments, proper head position is very important. Why do a lot of guys use wind covers at the intermediate levels, because it "Looks Pro."

Last week at a local A and B Crit. A guy won in the Cat 4/Cat5/open womens div. race with a steel Iron Horse frame with Shimano 105. His bike weighed approx. 5 to 6 pounds more than most the bikes on the course. My thought on this subject! Until you become faster than your bike, no since in buy all that crap. Become faster than the performance of your bike before you go buying Aero accessories. If there is one item that holds a stong argument is Aero bars, which force a more aerodynamic position when riding.

Some will tell ya, it all adds up. A local Doctors son who races a 16.5 pound Casati with all the bells and whistles has yet to finish top three long as ive been racing. His bike is way faster than he is. If you have money on Aero accessories spend in coaching first.

Peace
