OneUp Announces NEW V3 Dropper Seatpost – Mountain Bike Blog Post

Introducing the NEW Dropper Post from OneUp Components V3: An ultralight, high-performance, long-travel dropper post.

Lighter, smoother and more reliable

Our third generation dropper seat post took over three years to develop. It’s better than the award-winning V2 in every way. It’s lighter, smoother and more reliable. It has the shortest stack and shortest overall length of any other dropper. This isn’t just the longest seat post to fit your bike. It’s simply the best.

The new V3 is the lightest continuously adjustable dropper on the market for any suspension travel. It’s even lighter than XC-specific lightweight droppers. The V3 is available in a wide range of suspension travel options and is suitable for all rider weights and riding styles.

We simplified and refined the design as much as possible and reduced the weight of almost every single part to make the V3 Dropper 60 to 70 grams lighter than our V2. The biggest weight savings come from our new hydraulic cartridge that never needs to be inflated.

The new V3 dropper is 238g lighter than a Reverb AXS, 155g lighter than a Transfer and up to 60g lighter than the 2-position Transfer SL.

You can save an additional 10g with our Ti Bolt Upgrade Kit.

Our drivers demanded improved seals and less play and gentler action. The new V3 offers all of these performance improvements in a simple, reliable design.

Cartridge: For a smoother action, the all-new cartridge requires 75% less leverage to insert and much less breakout force to fire. This means you can drop the saddle even faster and easier while riding.

Bushings: We converted all bushings to a low-friction, self-lubricating IGUS material and increased the bushing overlap to further reduce friction. 180-240 drop posts feature an additional socket to further support the larger overlap.

Seals: We’ve developed an all-new high-performance collar with a bespoke SKF wiper seal to keep dirt out and grease in. The new seal and bushings ensure the V3 runs quieter for longer and requires less maintenance.

Pins: To eliminate rotational play without increasing friction, we doubled the number of anti-rotation pins and added 2 oversized polymer pins.
