Subject: RE: areo barsWhen you put aero bars on a road bike, make sure you get a proper (tri ) fit.
Most road bikes are longer, seat-to-handlebars, than a tri-bike. Then, when you put aero bars on, you can wind up reaching too far forward, flattening your hips and losing power.
From what I've read, when in the aero position, your forearms should be roughly parallel with your chest, with your elbow and shoulder forming right angles. Hip-to-heel should also be about 90 degrees.
My wife's road bike (which I'm using for triathlons ) has Syntace C2 clip-ons, and they seem fine. It actually helps that her bike is about 1 inch shorter than my touring bike, which means the aerobars make a perfect fit for me.
As with anything in triathlon biking - make sure you've got a good fit!
Slowtwitch has a good article on Tri-fitting a bike. Paragraphs 7-13 or so talk about the aerobars.

Once you've got the right aerobars, of course, you can enter the "which-shifters?" argument - on the hoods (like a road bike ), or on the aerobar bar-ends. Great fun! |
