I'm putting together an older Kilo to use to train on. It has the seattube extension that extends beyond the top tube. My question is where should the minimum seatpost extension line be?
It would seem to me that it would have to be below the intersection point of the seattube and top tube (just imagine the extension was not there) or else there would be a great risk of cracking the frame. I looked at the Cervelo site, since the original Eyres had a similar extension and there is a mention that there was a potential for incorrect seatpost insertion on frames such as these - Trek Hilos have the same type of seattube.
Any input appreciated.
