It is infinitely amusing to me to call professional athletes "abnormally big." I know what you mean, but it is still hilarious.

This an interesting article I read a while back, especially in light of a recent discussion we had about mavic comete/io vs. Zipp wheels: Relentless Pursuit of Cycling Aerodynamics ? Part 3. Track Bike Aero Test. - Fit Werx

I think fork wheel interaction is still not fully understood or tested. I recall seeing somewhere that the fastest fork ever tested was a flat bladed high tensile fork off of an old Schwinn? with massive clearance. Perhaps using one of these on an Io would actually make the io faster than an 808.

Maybe they discovered the gains weren't significant enough to justify the expense.

I'm watching the London SixDay, and there are a bunch of guys on aluminum bikes - including Ben Thomas, the madison world champion, who is riding a raw frame with labels I can't make out. He's also on the new Look alu frame, the 875 Madison. Won a derny race on day 2 riding it.

You got it backwards. The round seatpost is the 3.5mm head phone Jack of the bike world. It's an accepted universal standard that always works and people want it back. It's only been removed to serve the needs of the manufacturers.

That's a great article. Even though the point on the test was to test skinsuits on the road, the fact that they used top world-level pursuiters and tested on the track makes it even more relevant for track riders!

It makes a lot of sense that most "aero" wheels perform very similarly at zero or very, very low yaw angles. It's higher yaw angles and crosswinds that were the reason people departed from the V profile deep wheels in the first place.

If you can find them, I bet those Blackwell Research 100 mm rims test pretty favorably compared to modern wheels at low/head-on yaw angles. I'd bet those would make a decent pseduo-front disc on the track, if they're stiff enough.

To answer the OP's question, 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. It's a common misconception that depth equals aero. While this would be true were all else equal, a 303 at 38 mm deep actually outperforms v-shaped rims such as the Reynolds and Shimano at 46 and 50 mm deep, respectively. As an engineer at Zipp, you may question how objective I am on the subject; however, this data is available on Analytic Cycling and has been replicated in Tour and l'Achteur Cycliste magazine tests. Look for articles in Inside Triathlon and Road magazines in the coming months, also. Last I saw, they were omitting some of the test results from our last wind tunnel test as they were concerned about offending advertisers.

As an aside, the Blackwell rim is produced out of an open mold in Taiwan and is thus available under a variety of other brand names...if you like that rim one of the other brands may be cheaper for you.

Even better the velotec suit is really cheap and apparently works quite well, I'd been eying one off for a little bit but expected a sub 100 britain dollar suit to be more show than go. Apparently not the case

That (guessing) alu frame reminds of T-Red bike because of the top tube/seat tube junction but the dropout is not same. Maybe a custom alu frame ?
