  • Brand-X Ascend Dropper Seatpost (100, 125 & 150)

    Precisely engineered to bring you fast and smooth operation on the trails, the Ascend dropper post will get you into the optimum riding position in a flash. This means you'll be primed for the upcoming terrain so you can attack a climb or descent without having to stop to change your saddle position. Designed for MTB frames with dropper post internal routing, it will give a clean look to your bike too.

    Ergonomic Dropper Seatpost

    This mountain bike dropper seatpost features an ergonomic remote lever that has been designed to run from where your front shifter normally sits. It's ideally suited for those running a 1x chainring transmission without a front derailleur.

    Brand-X Ascend Dropper Seatpost

    Your bike's frame must have internal dropper post routing for seamless compatibility with this dropper seatpost. To eliminate cable movement/pull, the smooth operating Brand-X Ascend 120mm & 150mm MTB Dropper Seatpost has been cable actuated at the end of the seatpost to deliver consistent performance.

    Remotes supplied are suitable for MTB flat bars with a 22.2mm diameter. 1x fits in place of the front shifter on left side and 2x fits perpendicular to the bar beside the grip on either side. For CX bikes that need a 31.8mm bar, this can be found here.

    Reasons to Buy:

    • Incredibly fast and smooth operation.
    • Gives you an optimum riding position.
    • Internal cable routing for a clean look.
    • Effortlessly remote operated.
