OneUp V3 Dropper seat post. 30.9 240mm

Lighter – V3 is 70g lighter than V2, with the biggest savings coming from a new hydraulic cartridge that's fully sealed and never needs to be inflated. This post is the lightest infinitely-adjustable dropper on the market at any given travel.

Long Service Intervals – 120 hours for clean and grease, 350 hours for rebuild.

Smoother – OneUp listened to riders who asked for improved seals, reduced play, and smoother action. They addressed all of these with a new cartridge, low friction bushings, and a new custom SKF wiper seal to keep everything running smoothly longer than ever before.

Anti-Rotation Pins – OneUp has eliminated rotational play without increasing friction, with double the number of anti-rotation pins of the V2. They've also added two oversized polymer pins.
