"]news:[email hidden]...Quoted message said:(Kraig Willet should be headed to the Texas A&M wind tunnel any day now...would be nice if we get
an AC 420 wheel to him to test.)I head out Sunday. No such luck in this case though - I won't be testing the AC420.
The trailing edge, and rim curvature near it, does matter. I can remember testing a 47 mm deep rim
that was so inefficiently shaped that it performed equivalently to a 25 mm deep rim.For the most part, though, (and I hate to generalize like this) rim depth is the primary
contributor to the reduction in body axis drag.Anyone wishing to read more on the topic can email me privately for the Greenwell paper (a wheel
aerodynamics article that appeared in a scholarly journal).
Kirk - not sure if you still read all this, but I'm looking for more information about what you find
are the best wheels out there. I have the Bontrager Carbons, but I'm not sure that their fairly
standard pofile is that aero. I'm just wondering if my money is better spent elsewhere. Thanks - a
