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.
Get the Most Drop.
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.
What size of dropper post will fit my bike?
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.
How regularly should I service my dropper post?
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.
Will this post be compatible with my existing dropper remote?
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.
Are the seat clamps compatible with oval carbon rails?
Yes, our seat clamps are fully compatible with 7x9mm & 7x10mm carbon seat rails.
The actuator, inside the post, doesn't line up front to back?
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.
Why is my post slow to extend when I actuate it?
There can be a few different reasons for slow dropper extension. The first checks should always be:
- Check seat collar is torqued no higher than 5Nm.
- Check the cable tension is correct and the cable is not kinked, binding or sluggish.
- Check the upper bushing is properly greased and there is no evidence of excessive wear.
If your posts continues to extend slowly then please email us at firstname.lastname@example.org and we will help resolve your situation.
Do you sell replacement upper or lower tubes?
We do not have upper and lower tubes available as single items.
What grease should I use to service my post?
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.
OneUp have managed to raise the bar once again with the Dropper Post V3. OneUp have made many significant improvements.
It's really cool when affordable new products come out that increase durability and maximize efficiency.
