The Coast Post combines the benefits of a dropper with the joint saving squish of suspension. This witchcraft all happens via a dual chamber hydraulic cartridge featuring 40mm of tunable air suspension, designed to help riders on all types of bikes - from packed up trekkers, to the cross country wanderers, even the weekday commuters.
Suspension + Drop
TUNABLE AIR SUSPENSION
The Coast Post features 40mm of tunable air suspension housed in the internals to make your ride a bit smoother. Some extra squish in your seat post can help soak up some of the bigger impacts before they get to your bod.
External & Internal Options
The Coast Suspension Dropper post comes with both External and Internal Cable Routing options. Each designed to keep your cables tidy and out of the way during up and down actuation.

The Benefits of A Dropper Beyond SINGLETRACK
Trekking and Gravel Bikes
The Coast Post serves dual purposes for adventure bikes, soaking up larger bumps on the trail, it can also help when you get on and off your bike when it's packed up with gear.
Commuting Ease
A dropper allows you to push a button and be in a flatfooted position when you want, while easily returning to you the best saddle height for riding once you get going again. If you’re not feeling your track stand skills, this can be great for starting and stopping in city traffic
E Bike Accessory
When your saddle is at the proper height dismounts can be inelegant, even more so when you’ve got the added weight of a battery system. The dropper can help you get on and off the bike, especially helpful if your hips are tight and creaky like ours.
How Does Travel Adjust work?
Our travel adjust system allows for a total of 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.

Reviews
Back and hip issues. Impressed with smoothness on the trails. Simply cannot be without this.

The light suspension is just enough to take the bumps out. Now I’ve got the best beer getter bike in town. PNW nailed this concept.
Geoffrey S. Verified Customer
Great dropper and has the added benefit of enough suspension to take the bite out of the bigger drops.
