Thanks for your thoughts on this. I agree that since I'm using a setback seatpost and my seat is all the way back, I think it'll fit. It's difficult for me to try out the bike since I live on Maui and none of the local dealers carry Cervelo. I'm thinking of ordering one through Competitive Cyclist, where I've ordered components from them before.

Any of you frame builders here have any ideas on this? Thanks!
