    Need assistance/suggestions for fixing the seat pan of my OEM Corbin seat. Specifically the rear hinge mounting point. The plastic that holds the retaining but cracked and now the seat is not connected at the team most point.

    Do you have a stock seat with the metal pan available? Years ago I took a Corbin, drilled out all the rivets and mounted the pad and cover on a standard metal K100/75 seat pan. Still got it.
    If you can't do it yourself, an upholstery shop can.

    Frank,


    You might want to go out and check that "stock" seat pan. Stock early Kbike pans were an ABS type of plastic just like the OP's. Some of the early Corbin pans were fiberglass. I have never seen a metal early K pan in the hundreds that I have seen.

    Can you post photos?

    You are correct, Lee. Memory failing me as the years pile up. It was/is a plastic seat pan and in my opinion, superior to Corbin's fiberglass pan.

    While Corbin, the seatpan is the OEM plastic version, not the Corbin fiberglass version. Hoping to find a solution that does not require a complete reuphostery at this point. Planning to do so in the future once I've landing on the desired seat upgrades (reshaping, etc.).

    You might be able to use a piece of sheet metal to form over the damaged portion and hold it in place with a couple of rivets.
