Time Trial / Time Trialling / TT

No. Depth is not a consistent guide to aeroness, and even sites which lay out the gains from specific wheel designs are rarely free from bias and hard to interpret given that the rest of your set up is unlikely to match the test rig.

Is there a simple website to see what you gain through different depth wheels?

My first thought in reading this was to chuckle and suggest the answer would be somewhere on the TT forum, but it would take months to find it.

But I had a thought yesterday which was that some manufacturers who make a range of rim depths produce data on their own wheels and how they compare to each other.

I looked at the Flo site recently and I'm pretty sure they have this. Obviously extrapolating from that to other makes of wheels has a bigger margin of error.
