What is the benefit of a reduced Q Factor?

Oh I know. Are you going to draw up a list of aero advantages in order; you can only have item 7 if you already have item 6?!?

Spending £600 on a pair of aero wheels to get a 1 second  per mile advantage for an Audax is not a logical decision nor could it be considered " worthwhile" by any sane standard. Buy some because you want them fine.  Riding on the drops would probably give 20x that advantage and cost nothing so if the object of the exercise was to either go faster or the same speed for less effort then a list with the biggest benefits at the top would seem logical.

I'd love some aero looking carbon wheels - something like on the Pinarello Dogma Carbon Bob 540 - Mavic Cosmics.

Why - because they look cool

Now chuck on mudguards, lights, odd-coloured bottles, carradice ...
