Here's how Landis set up his aerobars:

Mechov probably set them up from looking at photographs. What I notice from those shots (and Landis has used pretty much this position all year) is that Floyd has a remarkably low frontal area. I'm not going to google up the link, but Landis has said that his position is partly a result of UCI rules preventing him from using the now-popular flat-bar position, roughly demonstrated by Menchov (I think he's doing it wrong). I believe the core of the problem is that Landis would not be able to comfortably get out and flat with his arms without moving his saddle illegally far forward. Despite that, he gets very good aero results from his position, which looks like a UCI-legal Obree "mantis" to me. -- Ryan Cousineau http://www.wiredcola.com/ "I don't want kids who are thinking about going into mathematics to think that they have to take drugs to succeed." -Paul Erdos |

Can't speak for T-Mob, but I have a picture from 1988 of the West German TTT squad using Porsche's wind tunnel, so it's not a German thing. |

No, all ProTour teams do wind tunnel tests these days http://www.tno.nl/industrie_en_techn...indt/index.xml I designed and built a wind tunnel for small components when I was working at a company designing flow detectors. So I have a little experience with airflow and detection. I've seen three photographs now of the Rabobank guys and unless those photographs were purposely staged to show the wrong sort of positions, I can't see how those positions could possibly result in good aero results. The open chest area in particular has been cited in articles about aero positions as greatly increasing drag. That's why Landis uses the tilted up bars to close that area up. |

Why would someone need a wind tunnel to tell them that? "Hmmm. How about this - let's create a big pocket against the broadest surface to block air flow." "Good idea!" R |

Rasmussen (also Rabobank) uses a position like Landis: http://www.cyclingnews.com/photos/20...ikes4/IMG_0469 "Tom Kunich" wrote in message oups.com...
