Good question. I guess it felt comfortable and bike felt responsive and handled nice, but that may be a novice answer! I’ve ridden aero bars but on a road bike for years. Is tthere a way to assess a fit more precisely? (Edited: I mean a formal fit session will do this, but I’m wondering more subjectively as the rider… if I bought the cervelo, I’d get a very formal detailed fit on that bike. But from a rough eyeball fit and test ride it felt like the frame/fit was good)
