OneUp Components V2 Dropper Post [Rider Review]

Our "Rider Review" article series features the honest reviews from verified purchasers of Worldwide Cyclery. They contain the photos, thoughts, feedback & overall review you are looking for.

The OneUp Components dropper has been popular ever since it launched a few years back. For $199 it is tough to beat, especially considering it allows you to fine tune your post length for the perfect fit. Our customer has tried just about every post on the market and finally settled on the OneUp Components V2 dropper post. Check out what he had to say!

Overview

Dropper posts have become an essential component to modern mountain bikes. My first experience with a dropper post was a 125mm fox transfer that put on my Santa Cruz Chameleon. I loved it right away and knew that all of my trail bikes from here on out would have seats that go up and down with a lever. The next bike I added to my quiver was a Yeti 130. This medium frame came stock with a fox transfer 150. These are two very different trail bikes, but it did introduce how the position of the seat affects your ride. The chameleon has a sub 73 degree seat angle and the 130 has a 77 degree seat angle, in line with the “modern” shift. The steeper seat angle makes for a better pedal going up, but the raised seat becomes more of an interference when out of the saddle. For this reason, I have found myself activating the dropper much more frequently over varied terrain, not just descents.

I have had zero issues with the 150 fox transfer, other than the remote, which has been replace with a PNW loam lever on the 130 and wolf tooth on the chameleon. With my saddle position slightly forward, the seat post was extended out far enough that left me thinking, “ how would this ride if I had the seat further out of the way?” I would loosen the seat collar and push the fox transfer all the way to experiment. I liked it. I think more is actually better. I have heard some argue that you only need so much seatpost drop, If that is true, than why are dirt jumpers and trials bikes designed to have the seat as far away from your taint as possible? I was convinced that this concept can only be a positive in trail riding, especially since your pedaling position is returned with a quick flick of your thumb. When I switched my cranks from 175 to 165 I had to extend the seatpost out further and this led me to start measuring for a longer dropper. I contacted yeti to inquire what the max insertion depth on the seatpost on my medium 130 frame. I was informed that the frame was designed to be used with a 150 fox transfer and was given the measurement for this seatpost. I looked at my frame and measured from the seat collar to the first interruption in the seat tube.

For Yeti, this is the switch infinity pivot system. I confirmed the insertion depth by dropping a static seatpost in the frame, taping off at the seat collar and measure. This came to a conservative measurement of 280mm. Now to select the best option to achieve the needed height and still allow the seat to be as far out of the way as possible. The Worldwide Cyclery crew has made some in depth videos on different dropper systems and that pointed me in the direction of the ONE UP product. ONE UP has charted all the measurements you need, and there is also the cushion of being able to reduce your travel if needed. I pulled the trigger on the 210 V2 for my medium 130 frame. Upon dropping this post into the frame and watching it insert all the way, I felt that I just received a passing grade on my math test. Install was similar to the transfer and made even easier that I was able to use the same housing. I will say the only clumsy part is that the cable bushing is not secure in the one up whereas the fox transfer clamps securely, so there is no wandering when sliding the cable through.

Noticeable Performance Differences

The OneUp dropper has no play. The fox transfer has lateral play. The fox transfer has slightly smoother actuation. The OneUp actuation improved once applying the included grease to the bushing.

Now to the biggest difference, the stack height. On paper, this should allow for an increased seat drop of 60 mm.

The actual drop was closer to 80 mm because the design of the one up allows the for further insertion.

Final Thoughts

Overall, I am very pleased with the change and the price was right to test my curiosity. I can now transform my trail bike into a kids bmx bike with the throw of a lever. Now for an inappropriate review: When this thing is out and fully extended, it is very stiff, firm, and great to sit on. It has great shrinkage factor and can be discreet enough that your taint won’t be threatened.
