Why We Like The Cascade Dropper Seatpost

The PNW Components Cascade Dropper Seatpost pays homage to the Cascade mountain range, home to some of the best riding in the Pacific Northwest. Featuring reliable coil sprung internals, tidy external cable routing, and multiple travel options, this post is an absolute workhorse that provides dependable up and down service for miles and miles to come. The 150mm and 170mm travel options have been updated with larger diameter stanchions that makes them both stiffer and lighter, as well as an added DU bushing to combat side-to-side seat wobble. Together these changes improve the post's reliability even further, giving you some much-needed peace of mind when you're out in the mountains, miles away from civilization.
