Hi all,

I just found this forum today, and it's great! So glad to know it is here.

I'm primarily into longer-distance triathlons (half iron and iron distance) and love my tri bike, a Cervelo P3SL. For the past several years, though, I get a lot of neck discomfort when riding more than 30 or 40 miles. The neck discomfort seems to trigger migraines on rides > 2 hours. I have signed up for Ironman Texas in May of 2012, and I think I'm going to ride a road bike for it rather than stick with the tri bike.

Are there any road bikes that you all know of that have less aggressive geometry than others? Any change from the aero position should be helpful, but I want to try to be as comfortable as possible. I'm looking for carbon fiber and I'm 5'2'. I would love for it to have 650 wheels so that I can swap in my 650 race wheels with a powertap, but there don't seem to be many 650 options out there right now.

Thanks for any advice!
