OneUp Components Dropper Post: Rider Review

Since hitting the market, the Oneup Components dropper post has been one of the most popular droppers we've seen to date. In an already saturated dropper marketplace, Oneup was able to make a big splash and bring quality and reliability at a reasonable price point. In this rider review, our friend John Wall gives us his impressions. Check it out!

Introduction

As an avid mountain biker and professional mountain bike instructor, I spend most of my riding time in the hills and valleys of Brown County Indiana and the beautiful mountains of the Northeast Kingdom in Vermont. 

I have had dropper posts on all my bikes dating back to 2003 when I first purchased a Gravity Dropper Classic with 3 full inches of drop! KS was next on my bikes, which didn’t have internal routing, and I was able to bump up to a 150mm drop. The external LEV and DX models required a fair amount of maintenance to keep them running smoothly with finicky cable tension adjustments. They also ran a little slow on return when temps dropped below freezing.

I finally got a frame with internal routing and a Reverb Stealth. After becoming frustrated with the constant need for bleeding and absolutely no function at all in temps below 30F it was time to ditch the Reverb and give the OneUp dropper a try.

With excellent measurement guides on their website, I calculated that I would be able to run the 170mm version on my 2015 Giant Trance which would replace the 150mm Reverb. Installation was a breeze without having to deal with a hydraulic hose and I was able to run it at full length with no shim.

Performance

I like an audible “pop” letting me know my saddle has returned to full extension so the adjustability of the OneUp return speed was a bonus by simply setting the air pressure for the desired speed. 250-300psi is the recommended pressure so after a few test runs, I settled on 285psi. It is extremely smooth going down, requiring minimal pressure at the thumb lever, and the return is snappy with a good pop.

I ride year round and have been testing it daily side by side next to the KS LEV on my Heckler. I can attest that this post not only functions at -6F, but it returns with gusto! The KS would get more and more sluggish in return the colder it got.

Final Impressions

I have been so impressed with this post that I purchased a second one for the bike I plan on purchasing this summer so I would be able to replace the stock Reverb before ever throwing a leg over it.

At $199 along with a 2yr warranty, you can’t go wrong with the OneUp dropper from Worldwide Cyclery!
