Short or tall, OneUp has you covered with their updated dropper seat post.

100 to 210mm of Travel - New OneUp Droppers in a Length for Every Rider

We've been obsessed with shaving every last millimeter from our new dropper posts so that you can run the longest dropper possible. The OneUp Dropper Post has the shortest stack height and the shortest total length of any dropper post with the same travel. No other dropper post can get your saddle lower. The OneUp Dropper Post is now available in 120mm, 150mm, 180mm, and 210mm lengths and all can be shimmed down in travel by either 10mm or 20mm. 


The OneUp Dropper Post has class-leading specs, innovative useful features and offers real value. Want more from your dropper? Get OneUp.

Total Length 

If you want to upgrade to a longer travel dropper post, you’ll probably be limited by your new post's total length or stack height, which is why we've minimized both. Our 180mm post is shorter than every 170mm or longer dropper and even some 150mm posts. Most frames aren’t yet designed around long travel droppers, so the shorter the total length of your post the more likely it is to fit your bike.

Stack Height

Say goodbye to the double drop. Many riders are forced to run a shorter travel post because of an interrupted seat tube or still have to use a quick release with their dropper post to get their seat low enough. Upgrade to a longer travel post, even if your current one is already slammed. If you are 5'11 (180cm) or taller, it's likely that you can run a 210mm post.

The updated remote has the same awesome lever position for ultimate thumb wrap and control but now has a more durable aluminum body and is available in 22.2, I-Spec EV, I-Spec II, and MMX clamp options, for perfect integration with your brake lever at no extra cost.
