    ISP Seat Post Cut , Fit ,Measurement Strategy

    Just bought a new 2018 Giant TCR with ISP. Size M.
    First question ; Do you have an ISP bike ? Have you cut one to size? What height determination did you opt for and what spacers length did you choose based on your saddle height measurements?

    Secondly; since there are spacers that allow for post clamp movement of 20mm ,( up + or down - total ), where is the optimal cut?
    Does one choose the middle range ? to allow equal movement in both directions, or are the spacers used only ( or exclusively )for further extending beyond the riders optimum saddle height.


    Opinions welcome Re ISP ....I will know more after a 1000 test miles of climb.

    That is no troll, that is someone that has lost his mind.

    He's going to hit a bump, first his seat post is going to break off, he is going to puncture his butt with the CF seat mast. Somewhere in that time frame he is either going to hit something, or ... his right chainstay is going to say, no mas, and that's going to let go, hopefully he's not in the middle of a downhill hairpin turn with a 100 yd droppoff over the guard rail. But maybe that won't be such a bad thing, at least he will not be in pain in a hospital for several months.
