Would this bike have a 27.0 or a 27.2 post. It appears the 27.2 post can be installed but feels a bit tight to me...Before I do any serious damage I'd like to know. I think it is a p13 model I am not sure. I see on the Sheldon Seatpost database that the 72 Paramount track is 27.2

I am hoping that it is going to be okay.
