I thought I recently saw somrone making a suggestion as to aerobars for someone tall. I stand 6’4" and am thinking of adding clip-on aerobars to my road bike. I searched the archives but did not find the right keywords I guess. If anyone has any suggestions I would greatly appreciate them.
Thank you.

It’s all a matter of comfort. As most people on this page will suggest, if you’re going to attach aerobars to a road bike, you generally want to go with shorter bars, rather than longer bars, if you’re well fit on that road bike. Of course, being 6’4", “shorter” is a relative term, so that really isn’t much of a limiting factor. The other point to consider is being able to get as low as possible (while still comfortable…and safe) while in your aerobars. That’s going to be a bit of a factor attaching to a road bike. My suggestion would be to get the lowest bar-to-elbow-pad height you can find, but with an adjustable length bar, so you can test things out and find a comfort zone. To that point, the ever-popular Profile Design Jammer or Jammer GT could work. Also, since you’re pretty tall (I’m 6’3" myself) you could check out Profile’s Airstryke or Carbon Stryke (preferred of the two since you could more easily shift them to a full tri-set-up sometime in the future), Ritchey’s new Prologue bar, or the VisionTech clip-on, which has a really low pad height. I’m leary of Deda’s single-clamp design for larger riders and, if you’ve never ridden on aerobars before, I’d lean away from non-adjustable bars (e.g. Syntace), in my opinion…of course, I may get raked over the coals for suggesting that. 
How dare you bag on Syntace!!!
rshwgo, I’m 6’4" as well and ride a road bike set up for tris (cowhorns and aerobars) With the seat angle I’m riding at, I wouldn’t want the front end of my bike to be any lower than I already have it set up. (It’s well below the saddle) I currently use Syntace C2 mediums as my aero extensions. Given that it’s a road bike, the top tube is a bit longish, so that plus the size mediums means my aerobars are about 1 cm longer than I’d like. I’m not going to go with a shorter stem (it’s pretty short already), and I also don’t want to go with the small Syntace bars as then the pads would be too far up my forearm for my tastes. So I guess I’ve had to compromise a little. I’m very happy with my current setup and fit, but it did take a couple seasons of tinkering.
