PNW Coast Suspension Dropper Post The Coast dropper is the worlds first Suspension Dropper Post, combining ride smoothing suspension and the benefits of a dropper into one seat post. This dropper is designed to help riders on all types of bikes, from packed up trekkers, to the cross country wanderers, even the weekday commuters. We developed the Coast because the earth isnt flat (no matter what those people on twitter say), its kind of bumpy. And while we all like coasting along on freshly paved roads, mountain paths are enticing and potholes exist no matter how much we swear at them. The Coast Post was designed to soak up some of these vibrations. We accomplished this via 40mm of tunable air suspension housed in the internals to make your ride a bit smoother. While this post provides some relief from everyday chatter it also comes with up to 120mm of drop. Most people associate dropper posts with mountain biking, but it turns out theyre pretty jazzy on everything from gravel bikes, to trekking rigs and commuters. Lets face it, when your saddle is at the proper height dismounts can be inelegant. A dropper post allows you to push a button and be in a flat footed position when you want, easily returning you to the best saddle height for riding once you get going again. This can be great for starting and stopping in city traffic, or getting on and off a bike packed up with stuff - or really, if your hips are just extra tight and creaky like ours. Plus when youre going downhill, a dropper easily gets the distraction of your seat out of the way, letting you lower your center of gravity. Not only does this put you in a safer riding position it also makes descents more fun (we wish this safer-but-also-more-fun combo was true for more things in life). NOTE: While the Coast is rad at what it does, it is NOT a replacement for rear suspension. The Coast's intention is to absorb larger bumps such as potholes, curbs and other impacts, it does not provide small bump compliance found in rear suspension mountain bikes.
