Short stack height, adjustable travel, good reliability - there's a lot to like about OneUp's updated dropper.

Tested: 210mm Dropper Post v2 from OneUp Components

We’ve already spent a lot of time on OneUp’s droppers and we know that they deliver awesome performance at a good price point. But these days, more is always better, so to create v2 OneUp went back to the drawing board and added this whopping long 210mm version to their arsenal of slippery sliders. We've had one out on the trails to test, check out the details and our video review below to learn more.

  • Adjustable travel

Video Review

The OneUp 210mm dropper post was reviewed in Vital MTB's Gear Show, jump ahead to 6:24 to view it directly (or just sit back and enjoy the whole show!):

 

What’s rad about OneUp’s droppers? First of all, they’ve proven themselves to be reliable, which is easily the biggest bone of contention many riders have with this particular piece of equipment. Dodgy droppers, no thanks! We’ve collectively paid our dues there. Now OneUp’s droppers also come in a variety of different sizes and lengths, and because they offer possibly the lowest stack height and total post length of any dropper out there, chances are you can squeeze more dropper travel out of a OneUp dropper than anything else.

Not only does OneUp make the v2 dropper in a bunch of sizes – you can also easily adjust the travel of your dropper in 10mm increments. The v1 version used a plastic shim that could be cut to a specific length to achieve this, on the v2 OneUp has moved to a system based on a set of small little brass spacers instead. The 210mm version tested here can be set to 200 or 190 by just unscrewing the collar and sliding in a couple of the aforementioned spacers. As for the remote, it comes with a separate clamp, or it can be attached directly to your brake levers if you run SRAM or Shimano.

On the trail, the action of the OneUp dropper is smooth, quick, and fairly precise. A distinct clunk lets you know your post has reached full extension, but it doesn’t shoot up like a rocket either. The remote is fairly easy to modulate, squeeze it to less than full travel and you can easily fine tune your saddle height. Our only gripe with the remote is that it is positioned a little bit awkwardly. It’s meant to mimic the placement of the smaller shifter lever (from back in the days when we all had front derailleurs, you’ve probably seen one in a museum somewhere). It sits in the right place which is all well and good, until you press it. It then ends up traveling a bit too much forward, leaving you to stretch your thumb to get all of it. Other than that, thanks to the short seat tube of my bike and my long legs, I was able to run the full 210 mm with room to spare. I did actually find it a bit too much, my sweetspot is probably more around 180-190, but that’s what’s so rad about this one – you can shim your way to your own preferred number. And if at some point your dropper should fail, the internal cartridge is user replaceable (for just $60 if outside warranty). All that for just $250 USD, including the remote, makes the OneUp dropper one of our top choices today. We have yet to update our big dropper post Face Off feature to include the OneUp, but when we do, it will clearly challenge for the podium.

About The Reviewer

Johan Hjord - Age: 46 // Years Riding MTB: 14 // Weight: 190-pounds (87-kg) // Height: 6'0" (1.84m)

Johan loves bikes, which strangely doesn’t make him any better at riding them. After many years spent practicing falling off cliffs with his snowboard, he took up mountain biking in 2005. Ever since, he’s mostly been riding bikes with too much suspension travel to cover up his many flaws as a rider. His 200-pound body weight coupled with unique skill for poor line choice and clumsy landings make him an expert on durability - if parts survive Johan, they’re pretty much okay for anybody. Johan rides flat pedals with a riding style that he describes as "none" (when in actuality he rips!). Having found most trail features to be not to his liking, Johan uses much of his spare time building his own. Johan’s other accomplishments include surviving this far and helping keep the Vital Media Machine’s stoke dial firmly on 11.
