OneUp's 3rd 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.

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

Smoother

Improved seals, reduced play and smoother action.

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: OneUp 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: The brand 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, OneUp has doubled the number of anti-rotation pins and added 2 oversized polymer pins.
