Hi all
Could somebody help me out with what total length dropper seat post will fit my medium 2018 Spectal 9 SL?

I need a 125mm drop but unsure on what total length I need???
351mm or 414mm??

    The answer to that question will depend upon what make of dropper you are considering. This might help; it is a link to a table of dimensions for a whole lot of different droppers.

    When it first opens look to the top right for a window that should open asking you if you want the french text translating. ... copique_v2

    Great thank you.

    Its the Rockshox Reverb Stealth, I have the 150mm at the mo but want to swap it out for a 125mm version

    If a 150mm fits then a 125mm will as the overall length is less (unless you raise the post so high you go beyond the minimum insertion mark).
