I had the upturned bars on my Trek E-7 last year and never quite got cmfy on them. I switched to Profile Design T2+ and I am the opposite of wesmeyer11, the instant I tried them I knew I liked them. Just feels more natural for me. I haven't had the pleasure of riding them outside yet, but I've done some good trainer rides including 1+ hours in the aero postion without coming up and have been comfy.

Try a pair before you buy them as is seems to be more of a personal preference type thing.

I had some Profile Aerolite bars stock on my bike. I didnt like. So I switched to T2s. They CAN be more aggressive, depending on how you use them. I like them because of their versatility. You can ride them in an all out power position, fingers wrapped underneath, wrists bent. OR you can ride them hands on top, palms down with just the pinkies on the side for control. I find this resting position much more comfy than any other position.

As suspected - mixed opinions. The best thing to do is go to a store with your bike and a trainer, slap the bars on and give em a whirl. You will know pretty much right away whether they work for you. I thought they would be great given many of the top pros are going S Bend, but in fact it was the opposite for me. Bars are a very individual thing, just like shoes, bikes, etc....What makes bars or anything the "best" is how they work for you, not Norman Stadler, me or Airborne.

I love my Vision S Bends, have trained and raced them since last summer when they first came out. No wrist problems and they definately help me stay flat and low.

Read the article and you'll see it didnt work out.

S-bends are awesome. I ride the HED integrated bar, and I'll never ride upturned bars again. I find them more comfortable, more aero, and more adaptable during a ride. You can sit back on the saddle and choke up on the bars, or sit forward on the saddle and get to the end of the extensions, depending on the terrain and your current comfort level. They're simply awesome.

LOL, from the article

After the wind tunnel testing, Ivan had to catch a plane back to Italy that evening. "There was a rush at the end of the test and I only had a quick moment to ask Ivan if he was satisfied with the day and what we found," Daubert said. "He confirmed to me that it's probably unrealistic to expect a miracle. I believe Ivan values what we learned in the tunnel despite the pains of coming all the way to America, testing the day after a hard stage race and then having to listen to far-fetched ideas (in a somewhat foreign tongue). He's a trooper." ""
