  • Awesome dropper
    Couldn't ask for much more really, especially the longer lengths that aren't available in other brands

  • Great seat post
    Easy to fit works well and so much better than the one my Trek came with.

  • Excellent value dopper post
    I read great things about the OneUP dropper posts & have been very happy with this purchase. After many reliability problems with Reverbs its nice to have a post that just keeps working. It works great. I got a 150mm post for my XC bike & it fits as easily as the 125mm Reverb & weighs the same also. & the price is unbeatable!

  • Replaced a 150mm dropper with the 180 Oneup because they have the same insertion depth.
    I have run it for 3 weeks and it has been amazing plus the extra 30mm of travel makes a huge difference. Great price and product.

  • Really good price on a pretty good post.
    I swapped out a Thomson Covert Elite and the Oneup has dropped 42mm out of my stack height so that’s 5 stars there.
    The build quality is good, 5mm hex, no fiddly little bolts, the one negative is if you have the post clamp too tight the seatpost either won’t move or has limited travel. Loosen the clamp slightly and all is well.
