Whatever looks the sexiest on your machine

 

When you look at it, it must look fast while parked against the coffee shop wall.

Believe it or not, my Chinese 50mm wheels were amazingly stable in the wind riding through Woodstock every day compared to my 30mm American Classic Victory 30's that had me out the pedals a few times

Seconded.

Aero is only going to make a difference if you are training and racing in a wind tunnel and that weight difference is so negligible that you could take a dump before you go riding and get a bigger weight saving.

There bogeral aero benefit to aero wheels below 45km/hr. Its all grams of drag.

Above that speed it gets interesting because then wind factors come into play.

 

So buy the best looking wheels that makes you want to get out and ride.

Just make sure they have Chris King R45 hubs.

That's not true though, is it?

 

The caveat is that deeper wheels are certainly beneficial at low speeds, but as you get deeper, you need to see increasingly higher speeds to justify the cost vs aero improvements. In other words, there's no point in going to 80mm wheels if you're not able to time trial at 60km/h, you may as well just go 60mm and be slightly lighter and better on acceleration.

All tests on aero wheels quote the performance gain above 42km/hr. There is a good reason for this in that there is no real gain below that speed. In some tests there is a slight gain from lift generated by the rim profile but its inconsistent. What isn't contested is that an aero foil shaped rim has lower drag than a box shape rim.

What sort of speed is the average A batch rider capable of? 38km/hr over a peninsula route?

Hardly worth fretting about how much drag the different sections is going to save you. I'd rather consider the control aspects in cross winds.

I'm all for the 38/50 combo for Cape Town.

Why not a set of both? It is all monopoly money anyway..

Please steer us in the direction of where this Monopoly money is to be found. I think we all would like to know.
