Now that we know it was orginally 27.2 we should be able to ream it to that, unfounately I aquired two 26.8 high end fluted seatposts not knowing the exact size oh well that's just the breaks of life - if you know where there are any other pictures of this model I'd appreciate it. It it just a little wierd that other than the decals nothing says Cinelli on the frame although the serial numbers coorespond to the Cinelli dating scheme.
