This is the lightest infinitely adjustable dropper post on the market. Even lighter than 2-position XC specific lightweight posts and suitable for all rider heights, weights and riding styles. Save an additional 10g with the Ti Bolt Upgrade Kit.
This is the best feeling dropper you’ll ever ride. It takes 75% less actuation force to drop your saddle, it has ultra low-friction, self-lubricating igus® bushings and a low friction SKF® wiper seal keep the V3 running smoother for longer, with less maintenance.
A simple and reliable low-maintenance design is insanely easy to work on at home using only the OneUp EDC multi-tool or three standard tools (14mm wrench, 2mm & 5mm hex). Plus, it has a super long, 350-hour interval between recommended services.
Whether you ride an XS or XXL, the V3 is the longest post that will fit your bike. It has the shortest stack height and shortest total length of any other post and offers 20mm of adjustable travel. Use our Dropper Post Length Selector to find your perfect post. Easy.
Every rider is different, with different frames and rider inseams, etc. Your best bet is to use our Dropper Post Length Selector. You will need: Your current ride height, the distance from the top of the seat post collar to the middle of your saddle rails. Maximum Frame Insertion measurement. You can find this by inserting a rigid post or tape measure into your frame until it hits an obstruction. Simply plug those into the calculator and we'll give you our recommendation of dropper length based on those measurements.
We recommend you do an upper bushing clean-and-grease every 25hrs of riding, a full clean and grease service every 75-100hrs of riding, and a full rebuild every 250-350hrs of riding.
Most likely, yes.
If your dropper remote is cable clamping (has a bolt to clamp the cable) then yes, it is compatible with our dropper. If your remote does not have a cable clamp bolt, you can purchase the Dropper cable/nut kit. It comes with a cable bushing that can clamp a cable. With this you can set up any none cable clamping remote.
Yes, our seat clamps are fully compatible with 7x9mm & 7x10mm carbon seat rails.
The orientation of the actuator is dependant on the threads in the lower tube. This means the actuator orientation, once tightened up, is arbitrary and different on every post. The actuator orientation cannot be changed without rotating the lower tube on the guide pins.
There can be a few different reasons for slow dropper extension. The first checks should always be:
If your posts continues to extend slowly then please email us at support@oneupcomponents.com and we will help resolve your situation.
We do not have upper and lower tubes available as single items.
OneUp droppers should be serviced using a light suspension grease. All droppers come with a small packet of Slickoleum, but any light suspension grease will do the trick. We do not recommend any lubes, including fork boost on our droppers.
A minimum rider weight of 50lbs is required to fully compress the post.
Make sure to apply force to the nose of your saddle, if you're close to that minimum!

"I love the V3. Already had the V2 in my first bike and got the newer version discounted for the second bike. Installation was easy and straightforward. Has a nice snappy feeling. And the price is really fair for such a product even without the discount. I am 179cm tall and bought the 180 mm one."
"I've only had the dropper for <2 months, but it was easy to install, works well and the remote in nice to use. The return to top is very fast, and has made me think my other droppers are lacking when switching bikes. it was interesting to look at the droppers in the group I was with in Czech 1 month ago; It was a lot of One Up's!! I also have the OnUp handlebar on both my Enduro and SL eMTB, which I love!"
"Unbeatable value for money, no air pressure to adjust, easy to install and smooth use. Gosh and want another one!"
"I've had 8 different droppers on all my bikes, but this one is better than anything else I've tried. It was easy to measure to reach the maximum drop length. Smart design of the saddle clamp and the seatpost itself was thicker than previous posts, which should make it more durable in the long run. Convenient that you can easily adjust the max travel in 10 mm increments without having to disassemble the post. It has a strong return and the remote was good too. With this, I could increase the travel from my previous dropper's 185 mm to 210 mm. Ordering, price, and delivery were all top notch."
"Vom ersten Kontakt mit dem Support über die Lieferung bis hin zur Qualität der Ware - PERFEKT!!! Besser geht es wirklich nicht!!! :)"
"I am happy with the V3 150 mm as well as the V3 180 mm on my other bike, best dropper. Fast delivery, they took my complaint about the price because next day after purchase it was 20€ cheaper and they refunded it. All praise for OneUp."
"Amazing travel for a 27. 2mm diameter dropper. My daughter weights only 25kg so she fights with the 20 kg-force minimum requirement but she solved it. The setup was quite easy and trigger is butter smooth. I'am planning to by one for myself. My only doubt that I shold rebuild properly like with every new stuff nowdays."
"I initially bought a V3 180 and determined it to be too long. I sent it back and ordered a 150 (just right). No hassles. Their installation procedure is super simple and their customer support is excellent."
"I have used my new dropper for 250 km now. It got insane power, so it fly up like a rocket"
"Ich fahre seit vielen Jahren die Komponenten und bin äußerst zufrieden. Bislang keinerlei Beanstandungen."
