So, in your snide remark and "clever" misspelling of my name, were you just doing the typical usenet
dork thing a flaming a stranger because you can, or just trying to inflate your ego? Well I guess it
really doesn't matter.
The reason I asked is because I don't know the answer, hence the question mark at the end of my
first sentence.
In fact, I'm training for something far more important than a world record, I'm preparing for a
personal best in a 40k (I'd like to do a sub 60min). At the moment, I think I'm going to fall around
2 to 3 minutes short (need around 40 more watts) and am looking for as much [cheep] aero advantage
to make up the difference.
I'm going to assume by "microscopic" you're trying to say that the difference between a 20mm and
23mm tire is not measurable physiologically and possibly analytically. Is this what you're
trying to say?

p.s. what's your best 40k TT time?
