This was bought as NOS and I have only test fitted it - its a bit tall so I'm selling on. there are light insertion marks on the post and you can see where the clamps have fitted a saddle - these are light and not deep scratches on the post. I'm sure you could polish these out if you really wanted to. I have never riden on the post as it simply stuck out a fraction too much for me. supplied with the original box, instructions and quality control certificate. 27.2mm fitment. overall length to the rails will be approx 300mm length of inserted part is approx 130mm it'll work better on a compact frame geometry or a traditional horizontal top tube road bike if you have long legs or aggressive fit on a smaller frame. many thanks sam
