31.6 OneUp V3 Internal Dropper Post 180mm

Product Description

The OneUp Components Dropper Post V3 sets a new benchmark for mountain bike seatposts. By shaving 60-70g off the previous version, OneUp has created a post that is lighter than many cross-country specific 2-position posts, while remaining robust enough for enduro and trail riding.

Maximum Drop, Minimum Stack

The V3 features the shortest total length and lowest stack height of any dropper post. This allows you to run a longer travel post on your current frame than would be possible with other brands.

• Tunable Travel: Every V3 post allows you to reduce its total travel by 10mm or 20mm using simple, tool-free shim pins. This ensures you can fine-tune your saddle height to the millimeter.
• Low Profile: A compressed stack height of only 30mm (25mm for 34.9mm diameter) ensures the post stays out of your way when the trail gets steep.

Reliability and Smoothness

OneUp has overhauled the internals to ensure the V3 runs smoother for longer. It features high-performance SKF wiper seals and self-lubricating IGUS bushings to minimize friction and prevent binding.

• Sealed Cartridge: The new nitrogen-charged cartridge is fully sealed, meaning you never have to worry about topping up air pressure. It is also 100% recyclable.
• Extended Service: With a 350-hour service interval, you spend more time riding and less time in the shop.
• Simplified Maintenance: The entire post can be disassembled and serviced in less than 10 minutes using standard tools like a 14mm wrench and hex keys.
