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 dropper is superb! I bought it to replace an older V2 (still works, I was just after a shorter stack), and I've got no complaints. Setup is easy, actuation and any necessary adjustments are simple to make. The post easily survived a recent desert bike tour, so I reckon it's good for anything I can throw at it! Thanks, OneUp!"
"Awesome dropper post. Thought I needed the adjustability but with the crazy low stack height it fits me perfectly. Low weight and rigid. Had to order the gen 3 lever and clamp else due to being out of stock. But got the complete one up setup. The only complaint I have and I'm reaching here is lack of a sticker to rep the company."
"Works much better than the one I had. I am using my original lever and it works great with the V3, The V3 needs about 1/2 as much travel to cause it to release making it much quicker to drop and raise. My only complaint it the drop is simply too much. I don't ever want to drop my post more than 2 inches. I bought the 120 but shortening it to the 100 causes the seat to be too low and buying a longer post would just allow for a wider range and not really accomplish my preferred setup."
"Really amazing system. This is my first time installing a dropper seat post and I was able to complete the install without any issues. The seat post works flawlessly and I’m excited to continue using it"
"Great components! Kind of disappointed that the 180 V3 dropper has more fore/aft play in it than my other 2 V3 150 and 210 travel one up droppers. Was the other reason aside from adjustability, as to why i replaced my bontrager. Is this normal ?"
"Rippin dropper! Love One Up components. High quality and user friendly serviceability. Got another 20mm of dropper on my Kenevo SL (from stock dropper)."
"Whatever holds the seat straight has a bit more play than I would expect. I love the arrows on the seat clamp that indicate which way is forward. The action of the shock is very good as well and the oneup lettering is a nice way to indicate seat height."
"Perfect, exceeded my expectations! Their customer service is top notch as well. I highly recommend doing business with these fantastic people/company."
"Lighter and faster than my previous post. Easy install. Riding is much better when you don't have to bounce on the seat to get it to rise again."
"The staff were very helpful to walk me through the process of returning when I ordered the wrong size and getting me the correct one. The installation was easy. The operation is smooth and makes all the difference to improve my technical riding. I look forward to many more miles of enjoyment."
