evo.com | OneUp Components Dropper Seatposts > OneUp's latest Dropper Post improves on what was already arguably the best on the market. The OneUp Components V3 Dropper Post is smoother, lighter, longer, and more reliable than ever before. It has been updated with new seals, better anti-rotation design, and a new cartridge. For bikes with shorter seat tubes this is the best news: OneUp's new dropper has the shortest stack and total length of every dropper on the market, while still delivering up to 240mm of drop! Long Service Intervals 120 hours for clean and grease, 350 hours for rebuild. 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. 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. 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. | OneUp Components V3 Dropper Post 2026 - 31.6x210mm
