OneUp are amongst the pioneers of long-travel dropper posts, so it makes sense that their V3 dropper is the longest-travel competitor in this test at 240 mm. At first glance, the V3 strongly resembles its award-winning predecessor, but what’s new inside? And how does the OneUp fare against the competition?

OneUp, a manufacturer from Squamish, Canada, started producing dropper posts a few years ago and have constantly expanded their lineup ever since. Their catalog now includes a wide range of tools, handlebars, pedals, and recently even hubs. However, their flagship product remains the dropper post, which earned a “Best Buy” recommendation in our last dropper group test and continues to enjoy great popularity.
To find out whether the updated OneUp V3 can impress and challenge the competition, we put it through the wringer in this comparison. Priced at € 300, it’s not the cheapest dropper post in our test field, but it’s the most affordable option with 240 mm of travel. The only alternative with 240 mm of travel is the FOX Transfer Factory, which costs a hefty € 149 more. Our test field also includes more affordable droppers with 230 mm of travel, like the SDG Tellis V2, with prices starting at € 280.

When it comes to travel options, the OneUp V3 Dropper Post leaves little to be desired. It’s available in 90 mm, 120 mm, 150 mm, 180 mm, 210 mm, and 240 mm, which is the version we tested. If you need something in between the standard lengths, you can reduce the travel by 10 or 20 mm at home. While this requires opening the dropper, the process is straightforward and doesn’t require special tools. The OneUp V3 is available in four different diameters: 27.2 mm, 30.9 mm, 31.6 mm, and 34.9 mm. However, the 27.2 mm option is only available with 90 mm and 120 mm of travel, while the 34.9 mm version doesn’t include the 90 mm variant.
Weighing in at 700 g, the OneUp V3 is one of the lightest droppers in the entire test field. At the same time, it’s the one that offers the most travel at 240 mm together with the FOX Transfer Factory, but the latter weighs 120 g more. Despite its impressive length, the OneUp V3 has a very short insertion depth of 342 mm compared to the 364 mm of the FOX Transfer Factory.
The V3 remote can be purchased separately for € 50 and comes with either I-SPEC, Matchmaker adapters or a standard clamp.
Fortunately, what you don’t have to pay extra are the internals – and they deliver plenty of value. The OneUp V3 relies on a closed cartridge, which requires little maintenance and less force to operate the remote – awesome! When servicing the dropper post, the cartridge can be replaced effortlessly, and the travel adjustment is simple too – all without the need for special tools. Routine tasks like greasing are equally straightforward. Additionally, the stanchion features more guides compared to the OneUp V2, reducing lateral play.



Particularly striking during installation are the tapered nuts on the saddle clamp, which make it a lot easier to mount the saddle than conventional barrel nuts. The remote integrates seamlessly into the cockpit, and with three mounting points, you can precisely adjust the distance to your thumb. A small but clever detail: the cable end can be tucked away inside the lever, which prevents it from dangling or getting in the way.
Pressing the remote, you’ll immediately notice the textured rubber surface, which provides excellent grip on the lever. Thanks to the smooth interaction between the remote and the cartridge, operating the remote requires minimal finger strength – a feature we really like! The OneUp V3 drops and extends smoothly without any creaking or sluggishness.
In terms of extension speed, the OneUP dropper stands right in the middle of the test field, with competitors like the FOX Transfer Factory and RockShox Reverb AXS extending even faster. However, the speed of the OneUp V3 is perfectly adequate and doesn’t feel like a drawback on the trail.
Throughout the entire testing period, the OneUp dropper post performed reliably under all conditions, inspiring above all with its “set-it-and-forget” approach – exactly what you want from a dropper post.
Conclusions about the OneUp V3 dropper post
Even after a few minutes using the OneUp V3, it’s pretty evident that the Canadian component manufacturer has been developing dropper posts for years. Offering the longest travel in the entire test field, it provides unparalleled freedom of movement on the trail. At the same time, the OneUp V3 is one of the lightest droppers in this test, and, with its shallow insertion depth, is the ideal choice for bikes with short seat tubes. During the test period, the V3 performed flawlessly and without any issues. For us, it’s the clear test winner.
