    Air 9 Size Question (due to dropper)

    Hi, I have ordered an Air 9 Size M but just now i realized that it probably won't fit my saddle height.

    The Air 9 size M has a seat tube length of 419mm.

    My inseam is 840mm and my saddle height is about 750 to 760mm.

    The KS LEV Integra dropper thats comes with the Niner is 340mm total length (according to the sales representative).

    So, 419mm seat tube length + 340 dropper total length is only 759 mm. But i have to take into account the minimum insert length (90mm) and mechanism length (29mm). Which should be 759mm - 90mm - 29mm = 640mm saddle height max!

    Which is a big problem. Am I doing any wrong calculations?
    The correct size for me should be an size L frame even though I'm only 1,73m?

    Please help !

    New question here.

    I have found a better KS dropper drawing.

    And also realized that the information I need is the MAX EXTENSION (F - in the drawing).
    So seat tube length 419mm + Max Extension 221mm = 640mm max height!

    Can anyone confirm the dropper post length/model that comes with the Niner Air 9 2018?

    It seems like that if it comes with the 100mm or 125mm travel model it wont fit me. But the 150mm or 175mm travel will work just fine.

    Niner replied my email informing that the dropper post that comes with the size M frame is the KS Lev Si 450/150mm
    I have found the drawing below

    It has a maximum extension of 321mm. So I won't have problems.
