Building an aero-wheelset?(2 posts)

Building an aero-wheelset?sdh

I've been toying with the idea of building my own wheels. My question -- What is the deepest profile rim available (not pre-built)? I have seen the Velocity "Deep V" (30 mm). Does anybody make deeper carbon profiles that are not pre-built? Does a 30 mm profile truly constitute an "aero-wheel," or is it merely a "semi-aero-wheel" (or is it all just semantics).

If anyone has numbers on drag as a function of wheel profile depth, I'd be interested. Thanks.

You can purchase Zipp 404 carbon rims separately. They are very light and have a 58mm profile. I have this wheelset and really enjoy them. My former wheelset was the Rolf Vector Comp with a 30mm profile. Semi-aero at best when compared to the Zipps. Here is a link that answers your questions about aerodynamics about different wheelsets. Good luck with your buildout. http://www.bicyclesports.com/technical/aerodynamics/watts_drag.html
