In the bike industry fashion is determined by the mud on your shorts and dust on your shoes. Yet, there is something undeniably satisfying about a freshly tailored suit, we designed the all new Rainier Dropper Post to add that custom tailored feel to your bike. Known for its consistency and reliability, this new iteration builds on these principles while fitting more bikes and providing refined adjustability for the rider.
Refined Adjustability
More Drop for your Dollar
Our tool-less travel adjust system is designed to maximize the amount of drop for your particular body and bike model. It’s super easy to dial in and allows for a total of 25mm* or 30mm travel reduction in 5mm increments.
Weatherpoof Sealed Air Cartridge
The Rainier Gen 3 rocks an updated cold weather proof cartridge - providing you unparalleled reliability across all sorts of trail conditions. Plus when it does come time to service it’s an easy no-mess process.

Shorter the Better
The redesigned Rainier is significantly shorter than our other posts. We scrubbed the overall length of the post providing some of the shortest insertion depths on the market.
How Does Travel Adjust work?
Our travel adjust system allows for a total of 25mm* or 30mm travel reduction in 5mm increments. If you were riding that line between travel sizes you can now fine-tune the perfect fit by following the easy directions below:
- Begin by lowering your dropper at or below the desired travel length (just make sure it’s not fully extended!)
- Unthread the midcap with your hand and slide it up to reveal the white DU Bushing.
- You’ll see negative numbers with corresponding notches machined into the post (each # represents decreasing travel.
- Slide the DU bushing up and rotate it to align the black arrow with the amount of travel you would like to reduce, then seat the arrow into the machined groove. (Make sure it’s fit securely into these notches!)
- After pushing the DU Bushing back down, lower the midcap and hand tighten (no need to go overboard!) and ride off into the sunset with the perfect travel for you.
*25mm of travel reduction in the 27.2mm diameter. All other diameters have 30mm of travel adjust.

service program

FAQ
Is this post compatible with my bike?
Start by checking if your bike is externally or internally routed. The Rainier is only compatible for internally routed frames. Second check the seat tube diameter. Want help finding the right dropper for your bike? Click here >>>
What is the tool less travel adjust system?
This system allows you the maximum drop for your post size. We accomplish this through a notched bushing under the midcap collar so you can dial in a more tailored fit.
How often do I need to service the post?
As riding frequency and conditions vary, we do not have a strict service interval. Instead, we recommend servicing your post if it starts to feel sticky/slows down. When it does come down to service it is a quick and easy, at home process.
What’s the difference between the Rainier Gen 3 and the Bachelor?
The main difference between the posts is the cartridge style. With the Rainier you get a sealed “set-it-and-forget-it” cartridge. The Bachelor has the advantage of an adjustable air cartridge, where you can customize your return rate.
