Delivery time: 5-7 Business Days


The lightest, longest, smoothest and most reliable dropper post that will fit your bike.

The V3 is the lightest infinitely-adjustable dropper post on the market, it has the shortest total length and stack height of any dropper post, 20mm of adjustable travel, an extended 350-hour service interval, and new ultra-low friction IGUS® bushings and SKF® seals. Plus, save an additional 10g with our Titanium Bolt Upgrade Kit.





This is the lightest infinitely adjustable dropper post on the market. Even lighter than 2-position XC-specific lightweight posts, and suitable for all rider heights/weights/riding styles.



This is the best feeling dropper you'll ever ride. It takes 75% less actuation force to drop your saddle, it has ultra low-friction, self-lubricating IGUS® bushings and a low-friction SKF® wiper seal to keep the V3 running smoother for longer, with less maintenance.


More Reliable

A simple and reliable low-maintenance design is insanely easy to work on at home using only the OneUp EDC Multi-tool or three standard tools (14mm wrench, 2mm & 5mm hex). Plus, it has a super long, 350hr interval between recommended services.


Maximize Drop
  Whether you ride an XS or XXL, the V3 is the longest post that will fit your bike. It has the shortest stack height and shortest total length of any other post and offers 20mm of adjustable travel. Use OneUp's Dropper Post Length Selector to find your perfect post.
