Sometimes you might wish a suspension seatpost could take the edge of a bumpy ride, and other times a classic dropper post is what’s needed to get your weight back on tricky descents. Now, PNW components has a one stop solution in the Coast – the world’s first suspension dropper seatpost!
PNW Coast combined suspension & dropper seatpost!
With more bikes getting dropper posts than just enduro & gravity-inspired trail bikes, there start to be more possibilities that just getting the longest travel possible. PNW Components out of Seattle like to put droppers on gravel bikes, adventure bikepacking & trekking bikes, even urban commuters. For a relatively minor weight penalty you get more control on steep downhills (plus extra safety & fun) or even just making getting on & off the bike easier.
Apparently, PNW got a lot of requests from gravel & hardtail riders to see if they could add a bit of cush into a dropper to smooth out bumpy roads & trails, and that’s exactly what they did with the Coast. On top of a pretty standard dropper post, PNW has added a second air chamber with 40mm of tunable air suspension.
Inside is a 2-chamber hydraulic cartridge that manages the post going up or down. A separate air chamber lets you control the stiffness of the suspension – lower pressure for a supple movement through the 40mm of travel, or high pressure to all but lock it out. Just thread a shock pump into the valve on the back of the 2-bolt head, and dial in your preferred setup.
The new Coast combined suspension dropper post is available in multiple sizes and routing configurations to fit pretty much any bike.
In 30.9 or 31.6mm diameter, the Coast gets 120mm of dropper travel, while a 27.2mm version drops back to 100mm. All three are available with internal routing, or an external actuation from the collar.
The two larger diameter posts sell for $179/ 192€ with either internal or external routing. The smaller 27.2mm post is a bit more at $199 / 213€. Several different remote levers are available for either flat or drop bar setups, adding a bit more when you buy the post. PNW backs all of their suspension/dropper posts with a 3-year warranty.
