Hi

I’m in need of a new dropper post after my one has died and is going to cost £120 to repair. I’m looking at getting a 150mm reverb that is 440mm long, my current x-fusion is 125mm with 420mm length. I ride with 60mm extra of my seatpost on top of the 125mm out of the seat tube so the extra 25mm of drop won’t affect me when on flats/climbs.

Added a photo for guidance. (Can’t take a better photo as bike is in shop)

What im worried about is having the full 150mm in the drop position could this bottom out on my seat tube/frame and cause any damage??

I would get another 125mm post but many companies dont seem to do anything in the 420mm post length, all seem to be closer to 390mm and due to my long legs that would put the post under the min inset line.

Cheers in advance.

    No, it won't bottom out when lowered.
    The stanchion is contained wholly within the outer part of the seat post. If it is ok when fully extended it will be ok when fully retracted.

    Check you can insert the longer post by the longer overall length, it only means pushing your current one down and extra 2cm to check.

    Late to this but a new seal kit for £20 will sort the Hilo and its easy to work on. You'll need a large strap wrench and oil.

    Just serviced my Hilo SL after it lost pressure ans leaked oil. New seals and its perfect.
