How Does Travel Adjust work?
Our travel adjust system allows for a total of 25mm 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.

FAQ
Is this post compatible with my bike?
The Rainier is for bikes with 27.2mm seat tube diameters and internal routing, to find out how to diagnose the best dropper for your bike click here >>>
Does the post come w/ internal cable & housing?
We include our cable and housing kits with each of our levers. When you order the dropper by itself cable and housing will not be included.
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. Check out our service video here >>>
