Can we talk about upgrading wheels?

[Owlie]

I don't need a really aerodynamic wheel. I am looking for lighter ones. Of course, anything would be an upgrade from my current wheels (the stock ones). I'm not regularly going fast enough for aerodynamic wheels to make a difference. I realize that I'll have to compromise performance and comfort.

I hear this all the time. I'm not sure what physics book people are using.
If it's the physics of cheaper is better, I can understand.
But I don't think you can say you want to upgrade performance without exploring an aero wheel.
Even if you do average 12mph. ( a dubious arbitrary # anyway..)
Given that almost all the work (70%) you're doing is getting through the wind and that the newest versions of top end aero wheels do not suffer from the same control issues of their older cousins. One shouldn't discount the option.

I run 25mm tires on Zipp Firecrest wheels. It's the fastest, most comfortable setup I've ever had.

DBF says that he never felt any benefit from aero wheels over a simply lighter wheel until he hit about 18mph+. Given that there are a whole bunch of factors there, well...
