Here are some infos that I'd like to share here and that I think might be helpful for beginners (and not-so-begginers as well...). I am a beginner myself and I passed a lot of time working on my aerobars setup in my basement before taking my bike out. For the first time, I tried my triathlon setup for a couple of hours and here's my experience :

I went out and did about 30km with my basement setup (15k back and forth on a cycling strip) and felt very uncomfortable with the position. This setup is very aerodynamic though and I thought it would be fast ! I couldn't keep the position for more than 10 minutes w/out having discomforts in the neck, lower back, etc.

After my first 30km, I changed my setup and put my stem with a positive angle, which rises the handlebars 1 to 2 inches higher, then I did the very same ride. I was more than comfortable and increased my average speed by 2.5 km/h (1.55 mph) with the same perceived effort... Though the latter position is less aerodynamic, I could use all the power from my legs, just like I do without aerobars. Furthermore, the bike is much more stable with the new position...

What the story says is that comfort may be more important than aerodynamics. I guess that I could get used to the new position and lower my handlebars over time but for now, I am more efficient with an higher position (hence less aerodynamic).

Hope this is gonna be helpful for those looking for the right position. All I have to say is that you should work on your position (or have someone work on it for you...) unless you feel very conformtable with it...

Christian.

Exactly. The purpose of a good aero position is to maximize speed, not minimize drag. Yes, by dropping the bars a little, maybe you'll save a little drag, but if your power output drops more than the drag drops, you'll go slower.

Thanks for the post Christ. I've been shopping for road bikes, and am leaning toward a more "relaxed" geometry because I think my back will be tweaked if I'm laid out flat for very long. Sounds like I might have the same setup in mind as you have.

Christian,
Was this performed on a Road bike with aero bars or a Tri bike?
