RR / TT wheelset thoughts?

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...

Thoughts?

Good price. No info on their hubs though.

Worthy of winning the tx state cat 3 time trial? :)

Holy Deep Dish Pizza Batman!

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?

Check out slowtwitch.com. This topic comes up about 1x/week.

You know, I've never seen any data on 100 mm rims, though I know Cobb did test the wheel. I do know that the 808 (82mm rim) has done well in tests. Also, the zipp engineer, who posts on here as Waldo, has stated this on the forum:

"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."

Cite sources please.

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:

fabian likes his 808's for RRs.

Not if we PM we don't.

The Edge 118's are a different animal from the OP's asking point.

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.

Man those HED 60mm wheels suck. Cross those off the list. The 90's fair a little better

No. No. No.

You're supposed to go to the grave insisting you were right. You'll be banned soon. You've broken the BF code of blindness.

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.

:lol:

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.

What model year HEDs are those? They redesigned for 2009, numbers are much different than prior models.
