OneUp Components V3 Dropper Post

The stack height is the distance from the seat collar to the saddle rails when the post is fully compressed. A lower stack height, like the 30mm found on the V3, allows you to run a longer-travel dropper post on frames with limited insertion depth or standover clearance.

Yes, the V3 features infinitely adjustable travel. You can reduce the total travel by 10mm or 20mm using the included shims, allowing you to fine-tune the post to match your specific leg length and frame geometry.

The V3 is designed for long service intervals. You should perform a basic clean and grease every 120 hours of riding, with a full rebuild recommended every 350 hours to keep the action smooth.

Yes, the V3 uses a fully recyclable cartridge system. If the cartridge fails or loses pressure, you can easily replace the entire unit yourself without needing to send the post back to the manufacturer.

The 34.9mm version is optimized for larger seat tubes and features an even lower compressed stack height of 25mm compared to the 30mm stack height on the 27.2mm, 30.9mm, and 31.6mm models.

Yes, the V3 utilizes high-quality SKF seals and IGUS bushings. These components are specifically chosen to minimize friction and prevent debris from entering the post, ensuring consistent, smooth operation regardless of the weather.
