RR / TT wheelset thoughts?
https://www.planet-x-usa.com/pPC82/10...-Wheelset.aspx
How much slower could a 101mm rear wheel be vs a disc wheel or a wheel with a disc cover?
Plus for $850, it seems like a great deal...

I'd love to see some data on wheel covers vs Disc. I have a zipp 404 PT that I will be using with a wheel cover from wheelbuilder.com at the State TT. I'll be leaving my Zipp disc at home in favor of power info. It makes me sad to not ride my disc.... As for front a front wheel, a pretty knowledgeable person told me that you need at least 80 mm on the front for a 40 K. So, I'm building a 100mm front wheel for the state TT right now. I found a Planet-X 100 mm rim (blackwell labeled) for only $150. I'm lacing it up with sapim cx-ray spokes to an American Classic micro 58 hub.

Didnt somebody do wind tunnel testing on these 100+mm rims and find them to be worse than 404's etc.. Edge never came out with their 100+mm rim after testing it in the tunnel right?

"the 808 outperforms the 100 on effective wind angles of 0-25° while the 100 is superior at 25-30°. With typical effective wind angles falling between 10° and 20°, the 808 is generally the better bet."

I have on some. See below.
Perhaps. Depends on the wind. The rear will be fine in any case.
I go down to an 85 or as low as a 46 in crosswinds. Otherwise I'll run the Stinger 9.

Don't we get in trouble for posting links to other forums? Troy? from Ligero Wheels posted it on a site dedicated to light parts 
Here is the quote I could find in my short amount of searching, there was more on the subject a while back..
and this:
(Zip/Hed Patent)
I did stumble across this photo and had a chuckle:

The 118mm rim that they were working has been tested in the tunnel and it did not do as well as expected. I was told they would be making changes to make it faster and there is no expected availability date because of the work that still needs to be done.
If they want to make a truly aerodynamic 118mm deep rim, they'll have to pay royalty fees. I don't think their is anyway to get around the fact that a rim that deep will stall out at fairly low angles without curved sidewalls.

Not entirely, any non zipp/hed wheel @ 100mm is going to have the same issue.. without the bulge you are going to have flow separation.

Here is some actual data:
Looks like I was wrong about the 101 losing out to the 404.

That graph is just awesome. The 101mm doesn't look bad at all... especially since you can get the entire rear wheel for $450 shipped.

I plan on using the 100mm front unless it's really windy. If it's too windy I'll just use a 404 front. Perhaps the 808 is faster in certain wind conditions, but for the money, these 100mm wheels procrit and I will be using can't be beat.
