PNW Range Dropper Post A dropper you can count on. In creating the Range Dropper Post, PNW Components set out to make a dropper post that riders can depend on, without draining their bike budget. This ultra-durable post is purpose-built to be reliable, easy to set up, and budget-friendly, for a dropper that does exactly what it should do, every time. The no-frills build of the Range mean that this post doesn't require the same level of maintenance as a lot of its competitors, giving riders more time on the trails, and less time at the shop. PNW uses a sealed cartridge design for the Range Dropper, so gone are the days of needing to top off the cartridge on your post before a ride. With easily-available spare parts, and a PNW lifetime warranty, the PNW Range Dropper is a dropper you can count on.
