    Sram grip shift to activate dropper seatpost

    I just modified a GX Eagle gripshift to do the job...so much neater than any lever since it complements my XX1 Eagle grip shift on the right

    Good job.

    Looking forward to hearing some longer term usage review -like does it eventually become intuitive or is it a pain to use in a real world situation of technical, last minute use.

    my 12 speed grip shift was instantly intuitive to use when I removed the trigger shifter...literally took me 20 seconds to get used to it...so the seatpost grip shift is exactly the same story for me

    Did you have to modify the shifter at all? Doesn’t the ratchet mechanism stop it from working correctly?

    I guess I'm just wondering how well one will adapt to attacking a downhill technical bit then having to twist and hold to lower or extend the seat. I'm sure it will be fine, but may take a moment to get used to how long to hold the grip in the 'pulled' position.

    To me, shifting is different than controlling the seat position in that a shift is just a click and the work happens after the fact whereas the saddle is a twist and old operation.

    the grip shift needs to be opened and the little spring loaded ratchet must be removed...

    twisting and holding momentarily to me is a lot easier and more intuitive than unhooking my thumb from a grip to push a lever

    3 rides down....works like a dream....I cannot believe this is not offered by SRAM or by anyone else yet...and at the price of a GX gripshift it will be difficult to beat...

    I once did this to see how it would work to actuate v-brakes instead of using a brake lever. Scariest test ride of my life.
    I would advise not taking my advice.

    I think this will only work depending on how the actuation cable is attached - at the lever or the seatpost.

    Using a LH GX grip shifter to actuate my dropper since early this year (with the internal ratcheting spring removed). Takes a few rides to get used to it, but now it's second nature.

    My Fox dropper put enough tension on the cable for the grip shifter to return on its own after actuation. Since switching to a BY Revive, it puts less tension on the cable so I have to rotate the grip shift back to its home position. I could play with the grease used in the grip shifter or try to add a return spring, but I'm used to it now.

    I know exactly what that is...and what it does...but what the heck is it called? (i.e. how do I search for one without 1 billion irrelevant results for "grub hub" delivery?)

    Knarp.

    'Cable barrel' or 'cable barrel nut' can work too.
    Do the math.
