The Coast dropper is the world's first Suspension Dropper Post, combining ride-smoothing suspension and the benefits of a dropper into one seatpost. 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 isn't flat (no matter what those people on Twitter say)—it's 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 they're pretty jazzy on everything, from gravel bikes to trekking rigs and commuters. Let's face it, when your saddle is at the proper height for riding, 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 you're 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). - Air Suspension: 40mm - Weights: 31.6/30.9 External routing - 615g, 31.6/30.9 Internal routing - 610g, 27.2 External routing - 540g, 27.2 Internal routing - 535g - Cable Routing: Internal - Cartridge: 2-chamber hydraulic and adjustable air - Lever sold separately - 3-year warranty - Perfect for commuters, gravel bikes, or hardtail bikes - NOTE: This is NOT a replacement for rear suspension, it is a suspension seat post that helps absorb the larger bumps while seated. It does not provide small bump compliance found in rear suspension mountain bikes.
