    Seat post plunger


    I would like to know the inside and outside diameter of the seat post plunger.
    The diameter of the plunger lock nut is slightly lower and it goes inside without screwing.
    There is something I do not understand.
    Maybe there are 2 diameters of plunger lock nut?

    A 45 seat post is 1" and the big twin is 1 1/8. maybe you have a big twin plunger and a 45 nut?

    I think you're right, the picture of the kit I bought.
    My question is:
    Where can I find the right lock nut?

    If it's possible to keep the kit.

    For $32, I wouldn't buy it either! You can usually find the entire assembly for around $100.
