I'm in the market for a new bike and I really liked the Bianchi Eros (specifically the steel frame and campy shifters). At the LBS I was sized in a 57cm, since on a 55 cm I was max up on the seat. I recently came across a great deal on a 57 cm 2005 LeMond Sarthe, which has better campy components and is a steel frame as well. My question is will this bike fit me? (I cannot test ride it). The top tube is 57.5 cm on the LeMond and 56 cm on the Bianchi, and the seat tube is 3 cm longer on the LeMond. I should probably just go ride a 57 Sarthe or Croix de Fer, but I don't think they have that size in stock. Any opinions/advice?
