The OneUp V3 Mountain Bike Dropper Seatpost is the ultimate choice for riders seeking the lightest, longest, smoothest, and most reliable dropper post for their bike.

As the lightest infinitely adjustable dropper post on the market, the V3 boasts the shortest total length and stack height, making it ideal for all rider heights, weights, and riding styles. It offers 20mm of adjustable travel, an extended 350-hour service interval, and features ultra-low friction IGUS® bushings and SKF® seals. For those looking to shave off even more weight, the Titanium Bolt Upgrade Kit saves an additional 10g.

  • Lightest Design: The V3 is lighter than even 2-position XC-specific lightweight posts, and suitable for all types of riders.
  • Smoother Operation: Requires 75% less force to drop the saddle, with ultra-low friction, self-lubricating bushings, and a low-friction SKF® wiper seal for long-lasting smoothness.
  • Unmatched Reliability: Designed for easy, low-maintenance care, it can be serviced at home with just the OneUp EDC multi-tool or standard tools. Plus, it offers a super long 350-hour service interval.
  • Maximised Drop: Designed to fit bikes from XS to XXL, the V3 has the shortest stack height and total length among all dropper posts, with 20mm of adjustable travel. Use the Dropper Post Length Selector to find your perfect fit.
  • Optimise your ride with the OneUp V3, the dropper post that sets the standard for weight, smoothness, and reliability.
