Dropper Post OneUp Components V3 30.9mm

Lighter, smoother and more reliable. Simply, the best.

Introducing the NEW OneUp Components V3 Dropper Post: An ultra lightweight, high performance, long travel dropper.

Our third generation dropper post has been over 3 years in the making. It's better than the award-winning V2 in every way. It’s lighter, longer, smoother, more reliable and has the shortest stack and total length of any other dropper. Now you get even more drop with a OneUp post.

Lighter.

The new V3 is the lightest infinitely adjustable dropper on the market at any given travel. It’s even lighter than XC specific lightweight droppers. The V3 is available in the widest range of travel options and suitable for all rider weights and riding styles.

We’ve shaved weight from almost every single part to make the V3 Dropper 60 to 70 grams lighter than our V2. The biggest weight savings come from our new hydraulic cartridge that’s fully sealed and never needs to be inflated.

The new V3 dropper is 238g lighter than a Reverb AXS, 155g lighter than a Transfer and up to 60g lighter than the 2-position Transfer SL.

You can save an additional 10g with our Ti Bolt Upgrade Kit.

Smoother.

Riders asked for improved seals, reduced play and smoother action from the V2. We’ve addressed all of these with the V3.

Cartridge: For smoother action, the all-new cartridge requires 75% less lever force when the saddle is loaded and much less breakaway force to initiate. That means it’s even quicker and easier to drop your saddle while riding.

Bushings: We upgraded all the bushings to use a low-friction, self-lubricating IGUS material and increased bushing overlap to further reduce friction. 180-240 drop posts have an additional bushing to further support the increased overlap.

Seals: We developed a completely new, high-performance collar with a custom SKF wiper seal to keep dirt out and grease in. The new seal and bushings keep the V3 running smoother for longer, with less maintenance.

Pins: To eliminate rotational play without increasing friction, we’ve doubled the number of anti-rotation pins and added 2 oversized polymer pins.
