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 and 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 at the time of order to suit your bike and saddle height. Simply select the number of travel-reduction spacers you would like to have installed when ordering and they will be installed by a Wolf Tooth factory technician before shipment. We also sell spacer kits separately for 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.

Patent-pending air external filter

The patent-pending external air filter prevents dirt and debris from entering the chamber so your Resolve Dropper Post can perform with smooth precision every time you need it. Because it is external, the air filter can easily be inspected and if needed, replaced with just a retaining ring pliers.

Reliable 2-bolt saddle clamp

Resolve Dropper Post is compatible with round and oval saddle rails. The two bolt design is simple, reliable and proven. The patent-pending Wolf Tooth design also enables the lowest stack height of any dropper post on the market. Optional titanium bolts and barrel nuts are available to reduce weight and add color.

Diameter can be swapped

The lower tube of the Resolve Dropper Post can be swapped to change between 30.9 and 31.6 mm diameters. You can buy a new lower section on our website and use video tutorials on making the swap, or you can send it to us and we can do the work for you.

Works in cold weather

We’ve been testing Resolve Dropper Post prototypes for over four years in all conditions. Expect precise, consistent performance no matter the weather, from desert heat to Minnesota winters at -20ºF and everything in between.

Smooth and refined operation

You need to trust your dropper post to perform when you’re riding. Resolve Dropper Post has smooth and refined actuation every time you need it. You’ll hear a loud, crisp sound every time it tops and bottoms out.

Beautifully CNC machined

We love CNC machined components here at Wolf Tooth and our Resolve Dropper Post is a perfect example. Even the parts you can't see are machined to a jewel-like finish.

"The Resolve is an excellent addition to the dropper post market, with best-in-class numbers when it comes to weight and overall length. The short stack height and insertion depth mean that more riders will be able to reap the benefits of a longer travel dropper post, and the fact that it's fully user serviceable makes it even better. "

"The Resolve post is a great introduction into the world of dropper posts for Wolf Tooth. It's a worthy contender against any existing options on the market. … We would certainly consider this post for our next bike build and would recommend it to anyone in the dropper post market."

"The self-bleeding cartridge works as claimed and it’s refreshing to have a seatpost that solves its own sag issue without having to intervene with a manual process, a rebuild, or worse, an internal cartridge replacement."

"I’ll be honest… I expected this dropper post to be good because it has the WTC logo. Those expectations can often lead to disappointment though as something is overhyped in my head. Not here. The Resolve Dropper Post as good as I had imagined. Better, really."

"The new Wolf Tooth Resolve is evidence that they simply keep getting better. In summary, it’s a quick, powerful dropper post that ticks all the boxes: it’s the lightest post and has the lowest stack height in its class, it’s self-serviceable and adjustable (both travel and pressure), and offers a really neat self-bleeding function that proved itself on the first ride."

"The Resolve dropper post is beautifully made and reflects Wolf Tooth's reputation for ingenuity inside and out. There's a unique take on saddle clamping to deliver the shortest possible stack height and a self-purging cartridge design that resets itself every time it's lowered. The post comes with the only rare tool needed to rebuild it, it's supported with service instructions and small parts, they're built in the USA, and are as smooth as anything on the market."

We believe in your right to be able to fix your components. Crashes happen, parts get misplaced, things go bump in the night. All individual parts are available as replacement parts. We also will service your Resolve Dropper Post here in our Minnesota machine shop.
