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!

"This is the best dropper post I have used. Install was very clean with the secure cable attachment. The low stack height is helpful with cable fit/routing on my Hightower V4, which has a very sharp turn. I love the pop up, and the clean retraction. Straight forward and secure interface with the seat."
"Got a 200mm travel version for my 2017 Santa Cruz Hightower and it fit with room to spare. Almost wish I’d gone for more travel. Great deal for a full kit with dropper + lever assembly + cable kit. Having 200mm of seat post travel is a game changer. Feels solid."
"I have waited and looked around for a dropper post and decided on the V3 from OneUp. Decision was based on 1) feedback from other riders 2) value 3) engineering/quality of product 4) options and easy tool to configure the right size post for my bike Been happy so far with the post and will probably buy more for a few more bikes in my stable."
"Bought a dropper post kit that included everything. Didn't come with instructions, but found some excellent videos on YouTube that walked me through. Came from a cheaper brand that came on my Ibis, and it creaked every time I rode, even after cleaning. The 1Up is very solid and strong. Well worth the cost!"
"This is the second seatpost from OneUp that I have bought, the first for my new EBike and the second for my son. I am so happy with this V3 dropper that I will be buying two more for my other two bikes and if my third bike wasn’t a DH bikeI would buy one for it as well. Dealing with OneUp as a Company is a pleasurable experience and I couldn’t recommend them enough. Go buy yourself a V3 dropper and fall in love with this Company and their products."
"Great dropper post! Very reasonably priced. Shaved a ton of weight ditching my AXS dropper post in favor of this. And no silly battery to worry about."
"OneUp dropper seat post works great, excellent smooth action and looks beautiful. This dropper seat post length is perfect for my Santa Cruz Hightower. I highly recommend this product to my friends and anyone who is shopping for a dropper seat post."
"I have had many dropper posts over the years but this is my first one from One Up. It’s definitely lighter than anything I have had in the past. Importantly, the 27. 2x90mm was the only one I found that I was confident would work with my 54cm Cannondale Topstone carbon frame which has limited seat tube space because of the kingpin suspension."
"Dropper is super quick to return. When you hit the lever the seat is where you need it so fast. I have OneUp droppers on all my bikes now."
"I've been riding road bikes regularly for the last 25 years . . . but actually began with my first road bike in 1965. I'm 250 and 6'3'' on a hard tail carbon bike - 2 knee replacements, 2 hip replacements and just had achilles repair which limits my movement on the repaired leg. Until the repaired achilles strengthens, I'm not riding technical trails but instead paved trails. Actually, very hard to get on an off my mountain bike without a dropper - the V3 is my first one. It has been a complete game changer (even for a guy who will probably never ride a technical trail again) even if all it does is help me mount and dismount without risking falling over. The length of the "drop" allows me to stay in the saddle and actually get both feet on the ground - for stability or for dismounting."
