I wonder what Cobb (et al) think about this ..........
Nah, what's interesting is that just like with Ullrich's position, people will radically change their current position despite having no knowledge of their aerodynamic or wattage profile and no way of knowing if they're actually causing harm or good.
Hence, style before effectiveness.
Yes, every ’89-ish aero bar positioning. I would guess that having the forearms pointing upward like that and elbows positioned close together, allows much of the wind that would hit a riders chest in the ‘Ullrich position’, to be deflected. The riders head and chest ‘hiding behind’ the outstretched arms if you will.
To me it looks fairly uncomfortable and un-powerfull. A person’s arms and shoulders have very little power/leverage at that kind of angle.
If you check out this photo, what's interesting to me is how his position would seem to block air from getting in around the torso. I'm no aerodynamic expert, but it would seem the "pocket" formed by the torso and hips would create a lot of air disturbance. But Floyd's position, with his forearms together, would force air around that pocket.
But how the heck can he breathe in that position? I'm all shoulders. I'd need all kinds of theraputic massage and probably accupuncture to get over riding for an hour in that position. It doesn't look comfortable to me at all.
If its at all comfortable I think a lot of people would be better off mimicing Landis. Not that its ideal, but i think less can go wrong with the mantis than with the current vogue.
We all had our bars angled up in the late 80's, early 90's, but much of that was because we were also using massive risers under the pads to get the front end high enough to be comfortable. This was a result of putting aero bars onto funny bikes with 24" or 650c front wheesl and tiny head tubes. If you look at Lemond's Kronostrada from the 89 tour or any of the Indurain TT bikes you will see bars at about 30 degrees, but with 2+" of pad risers so the effective arm angle was maybe only 10 degrees or so. I've definitely seen angles between 0 and 10 work for people as it has a way of flattening out the back a bit for some folks, but the Landis position would not seem to work for most people.

The fact that one wants to to be as aero and powerful as possible - AND conserve energy with some sort of muscle suppleness (?) for the run, makes our bike set-up a somewhat different kettle of fish (apologies to Paul Sherwen).
