Seatposts

Such Great Heights The budget-friendly Aeffect R Dropper Post is a rock-solid, shred-ready entry into the dropper post world. Designed right to keep you on the trails and out of the shop as much as possible, you'll wonder how you ever rode without one. It's What's Inside That Counts The brains of this dropper post are an extremely reliable cable-actuated hydraulic cartridge that delivers infinite adjustment within its travel. Simple Saddle Setup A user-friendly zero-offset seatpost clamp really cuts down on the time between setting up your saddle and ripping down the trail.

The OneUp Dropper post is available in 120mm, 150mm, 180mm and 210mm lengths and all can be shimmed down in travel by 10 or 20mm.

No other post can get your saddle lower. Starting from $199 USD with free shipping worldwide, cable actuated with reliable sealed cartridge internals for easy home servicing and includes travel adjust shims allow you to custom tune your post to dial in your perfect length.

The Wolf Tooth Resolve Dropper Post is the first dropper post to use a self-bleeding cartridge. It has the shortest stack height of any dropper post on the market, has a short insertion depth, is one of the lightest dropper posts, and is completely serviceable at home. - Self-Bleeding Resolve Cartridge: At the heart of Resolve Dropper Post is a self-bleeding cartridge that removes air from the fluid chamber with every actuation. All dropper posts can get air in the chamber, which leads to sag and squish. Resolve Dropper Post is the only dropper post that purges air from the chamber, which means you'll never need to buy a new cartridge as you do with all other dropper posts. - Shortest Stack Height: The shortest stack height of any dropper post means that Resolve can get your saddle lower than any other dropper post. The lower your saddle, the more room you have to maneuver your bike on drops and techy descents. - Weight and weight per travel is equal to the best: Resolve Dropper Post is one of the most lightweight dropper posts on the market when it comes to grams per millimeter of travel. It's as much as 26% lighter than other dropper posts of the same travel size. - Short Insertion Length: When a dropper post has a short insertion length, longer travel options are unlocked for more bikes. A short insertion length is vital for smaller bikes, frames with curved seat tubes, and frames with seat tubes that have bottle bosses. - Travel Reduction with Spacers: The travel length of your Resolve dropper post can be customized in order to suit your bike and saddle height. Spacer kits are sold separately or those who would like to have the adjustment made later by their local shop mechanic. If you are comfortable with working on suspension components, you may be able to complete the installation yourself.

Resolve rev2 expands the best-in-class, first-of-its-kind specs of the original Resolve while adding 34.9 diameter, a 242mm travel option, and new internals for 25% lighter actuation and better self-bleeding. It’s lightweight, keeps a low profile, and will perform as expected every time it is needed. It also has a low lifetime cost of ownership because it is covered by Wolf Tooth Right to Repair and is serviceable at home. At the heart of Resolve rev2 is a self-bleeding cartridge that removes air from the fluid chamber with every actuation. All dropper posts can get air in the chamber, which leads to sag and squish. Resolve is the only dropper post that purges air from the chamber, and rev2 features even faster self-bleeding when compared to rev1. Resolve rev2 is one of the lightest dropper posts on the market. It’s as much as 26% lighter than other dropper posts of the same travel and size. The short insertion length unlocks longer travel options for more bikes. A short insertion length is vital for smaller bikes, frames with curved seat tubes, and frames with seat tubes that have bottle bosses. A super low stack height gets the saddle down and out of the way for more room to maneuver on the rowdiest terrain.
