George, why buy used if this thing is 1900 bucks, if you fit a 54? What's not to like, 11 spd Shimano and this thing shifts flawlessly. Again, race bike, so be careful. Tell you the truth, you will like this thing after you actually ride it.

I bought two frames from these guys over the years. They carry good stuff.
