The Brand-X Ascend dropper post is one of our favourite products here at the Bikerack. Not only is the Ascend post Affordable, durable and reliable but it also outperforms many much more expensive seatposts on the market. It's no wonder most of the staff here have one on their bike.

We think a dropper post is the best upgrade you can make to your mountain bike and at this low cost and performance, it's hard not to choose the Brand-X ascend dropper post. 

This model is designed for bikes with internal cable routing for a clean integrated setup. Coming in 30.9mm and 31.6mm sizes and with a choice of 125mm and 150mm of drop there's a post to fit almost all bikes. 

If you're a longer-legged individual, check out the Brand-X Ascend XL Dropper post for 170mm and 200mm options. 

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 125mm & 150mm MTB Dropper Seatpost has been cable actuated at the end of the seatpost to deliver consistent performance.
