I don't agree. First, Because it depends on the time frame that's measured, by which I mean the wheels will not make you 1mph faster continuously over the course of a ride, but yet at any given moment, you could be going 1mph faster or more.

It all depends on what you do with the aero advantage; do you want to save energy (watts) or do you want to have more energy to put into going faster? Do you want to parcel out the extra energy over the course of a ride, or do you want to be fresher for a single, explosive effort?

I think that failing to understand that aero advantages are working for the rider all the time is the key point people miss. In this thread we've seen the claims that one has to be traveling at certain high speed averages to take advantage, as if it's only the ride total numbers that matter, and not that hard 5 minute effort that gapped you off the front and made you the first person into the regroup area, or that intense 45sec effort that let you nose across the finish first simply because you had that bit more energy and that bit less drag when you went digging.

Wheels are not some magic potion, but when you're putting it all together in your moment of truth, you need them on your side. Unless of course one just doesn't ride that hard, which clearly many here don't.
