• The seat post looks a bit smaller than the right one, seat lug is distorted
    while been loose (~1/3mm) front and back. That will allow a small movement to
    seatpost that eventually wear off seat tube.
    I 've seen those lugs in many bikes build with columbus SL. All of them have a 27.2 seat post.

    Except its boring silver, looks like a descent road bike in good condition.
