Originally posted by EchoLkScott I'm with Left Brain on this. The aerodynamic drag increases with the square of the velocity so it become far less important at lower speeds. All else being equal, the aerodynamic drag at 18.4 mph will be nearly 20% less than at 20 mph. Other factors (rolling resistance for example) don't exhibit this quadratic dependence on velocity.

If you run the numbers, you will see that aerodynamic improvements will still make a significant difference below 20mph. Shane
Yes, that and the fact the slower riders are on the course longer, so while the improvements are not as great as a % for slower riders, the absolute number of minutes saved is actually larger.
I know that gets said a lot, but isn't that the equivalent of saying that slower athletes are really just getting their money's worth for the race fee?
"These wheels are really fast and we can prove it with our tests from the A2 Wind Tunnel. We developed an ultra-fast modified V-Notch rim shape which keeps drag to an minimum."
My back wheel needs to be trued up. It has a slight side-to-side wobble, and I feel at times like I'm going to lose control when I ride. Is this something that I should only trust to my LBS to do?
The wheels are my first area of concern and I have started to shop around. I find it nauseating to think of spending the same amount for wheels as my bike. Any help?
Don't know how to take that rear wheel off of your bike? Is the chain making things difficult? Learn how to remove your rear wheel if you have to change your bike tire or fix a flat.
This article estimates how much time can be saved in sprint races by converting from stock aero wheels found on most tri bikes to more aero disk and composite spoked wheels.
