Good interview. I think Adam will be very well received by Triathlon as his personality actually fits in quite well with the typical triathlete. I like that he's questioning traditional thoughts/beliefs. Some paths will lead to discovery...others not likely, but at least he's trying. With clothing, for instance. His question about boundary layer trips on the arms is valid, but I believe what we'll eventually realize is optimized aerodynamics for clothing will be highly dependent on individual position; specifically, position of both the forearms and upper arms. In the end, if you want optimal, it will be designing a custom piece of clothing around a specific athlete's position, which would be costly, but effective. That's, of course, before you take the helmet and it's interaction with clothing into consideration. Oh, and it's really tough to "kink" arteries and veins sufficiently to decrease blood flow. Compression? Yes. Reduced blood flow from acute angulation? Highly unlikely from a bike position. Still, interesting question!

It might be picky to point out UCI rules, but even for USAC stuff I don't think you can show up to a Cat 3 or faster TT on an Andean, Ceepo, or this thing.

The last time I checked (which has admittedly been a while) USAC TT equipment rules for any events that don't select for international competition, and aren't national championships, can be boiled down to "don't ride a recumbent". Short of that, basically anything goes (including wheel covers to create a "disc").

So, there'd be no problems with Hanson showing up with this bike for ALL of the other USAC TTs. So, break out the Boardman era Lotus and have at the local monthly TT ;-)

I've often thought of setting up a TT rig with the Obree "egg" position and doing some local TTs with it...

Jim, thanks for the follow-up and the feedback.
Agree with regards to clothing and helmets and even your comments about blood flow. The reason I think it's a valid concept to consider is that we look at the minutiae of so many aspects of performance – even to the point of working with compression etc – but some positions to put severe limits on flow... Adam's response regarding Italian footwear was a great answer, in my appraisal.
If there's an shiatzu specialist or an acupuncturist in this thread, perhaps they could chime in with their thoughts. (It's a little pet topic of mine... and, of course, I'm completely open to the opinion of others. But, as I said to Adam, it's worth considering as it matches his penchant for outside-the-box thinking.)

I think Adam will be very well received especially here on slowtwitch as it will give everyone something to talk about and interest will be high. I am lucky that one of my best mates is a close friend who met when when he first competed in triathlon so I got to meet him and ride with the team post stage at the tour down under. I often get insiders before they come out in the media. Regardless he is a legend of cycling, has a good clean name in the sport and is engaged not only to be an athlete but in developing what will be quite radical equipment so I am sure he will be received well by the triathlon community. Everyone wants to see what he can do on the bike in an IM and this will only make it all the more interesting.

What's the current narrowest tri bike? I recall Look having a really thin bike but I was struggling to find details. My Omni is ~38mm everywhere but the fork, stays, and bottom bracket. Hard to imagine going thinner than that. Also, in theory the benefit of the side fork was hiding the rotating tire from the wid. This leaves just as much tire exposed. Maybe Ceepo got that one wrong though.

I have two Chinese frames; one is 28mm wide and the other 25mm wide, on the downtube and seattube. I also have old Trek TTT that is 30mm wide.

The headtube is wider though. On the Trek the headtube is only ~40mm wide because it has a 1" steerer. The one with a 1-1/8th steerer is ~48mm wide, and the one with a 1-1/2 lower bearing is 60mm wide at the bottom. Your Omni is really only 38mm even at the headtube?

Went back and inspected it more closely! Turns out it has a very slight taper in width from the front to the back. Hadn't really looked for it before as it's very slight. My rough tape measurement (not sure where my digital caliper is) shows 1 11/16", or about 43mm. That does make a bit more sense considering the width of the steerer alone!

I like his out of the box thinking. He's smart and experienced in working with carbon. I'm not sure the frame design will make too much difference but the drivechain idea is very interesting. Mike Burrows floated the idea of an enclosed drivechain in the 90s when he designed the Giant mcr. With electronics developments I think that could be very cool.

For perspective, steel frames (Columbus SL) are 31.7mm at the head tube, and 28.6mm at the seat and downtubes (ignoring lugs, 1" headsets, and BB shells).
