Overview of the OneUp pipette with 240 mm stroke

Is there such a thing as too many pipette movements? Most of us would say no, but then again, most of us haven’t ridden 240mm up and down. As a tall rider, I’m constantly on the lookout for a longer travel drip pole, and after testing this one from OneUp, I feel like it’s the day after Thanksgiving dinner: I’m satisfied and not sure I’ll ever be able to eat another one. rooster.

OneUp Dropper Publishing Specifications

OneUp only offers one dropper post model – the current one officially known as the V2 – with three diameters (30.9, 31.6 and 34.9mm) and six stroke lengths from 90mm to 240mm. Each post offers travel adjustment, which means if 150mm of travel is too high, you can reduce it to 140 or 130mm to match. This means there are actually far more than six travel options available, and riders will find they can use every last leg of the trail that their bike and leg length can handle. My test sample is a 30.9mm pole with 240mm full travel (no spacers).

The internal air cartridge has adjustable pressure from 250 to 300 psi so riders can adjust their desired return rate. There is a fairly standard two-bolt seat clamp on the top, and on the other end the actuator dispenses with the barrel nut clamp for ease of installation. Overall, the OneUp drip stand uses a design that should be fairly simple for most home mechanics to maintain themselves.

I had no trouble fitting the 240mm stem on my hardtail thanks to the long, straight seat tube. However, even with my XL body size and long legs, I only have about an inch between collar and ring.

My drip stand weighs 649g plus another 111g for the OneUp drip stand remote control (sold separately) and cable.

OneUp, 240 down

Compared to the 200mm-travel dropper posts I’ve tested, the OneUp 240mm dropper post feels very different, like I’m somehow sitting under my top tube. Basically, I think the head tube is a good couple of inches above the saddle by the time it reaches the head tube. On a hardtail and with the saddle pushed forward, there is no problem with saddle-to-tire rubbing, but I believe this can be a serious problem on a full-suspension bike. Riding the bike this low makes me feel super in control on steep descents and especially on tight trails. In the fully lowered position, my knees are bent as much as I would like; a little more and things can start to get uncomfortable.

At first I found the seat to return a little slow and figured I needed to add a little more pressure to the cartridge. However, with the extra 40mm of travel, I think the OneUp dropper post is just as fast as most others, it just needs to travel more distance.

Earlier this year, Matt looked at why 34.9mm seatposts are becoming more common, and the biggest argument in favor of them is that they allow the post to be lowered…
