Hey Jen, do the aero bars work well on Oscar? I have been considering doing that with my Felt and selling my Litespeed Saber. If I sell it though I will have to change my name to Carbon Guy, or Velo Nole.
They work very well for me because of the S2 geometry and because my frame is (ever-so-slightly) on the small side. I can get a good position on them, no problem, and they're very comfortable. I know if you have a longer top-tube, you may feel stretched out on your standard saddlepost.
