Just curious is there any breathing/exericing difference between riding on a road bike with aero bars and a tri bike with aero bars?
I have heard most riders are squishing their middle too much with a road bike and normal aero bars, and a tri bike is supposed to solve this problem.
Well, does it???
Not necessarily. If a rider is "squishing their middle", it means that the distance between the seat and the aero bar pads is too short. But positioning is such a rider-specific thing. Lance Armstrong looks like he's being squished in the middle but it doesn't hurt him at all. 4 factors control this distance:
1. Seat fore/aft position
2. Top tube length
3. Aerobar arm pad position (some arm pads are right over the stem, others are further back)
4. Stem length

I asked this same question of T-Mar in the vintage forum. He had lots of good advice. I put aeros on my very relaxed Peugeot U08, circa 1968. The geometry was unmanageble. I could ride with less wind resisitance for 10 to 15 minutes at a time, but inevitably needed to sit up and get back in the drops to be comfortable. I am happier going a bit slower with more comfort at the level at which I compete.
A tri-bike with aeros would be a significant advantage in my situation.
