In the last ten years, there have been a number of standout technologies that have improved mountain biker's ride experience. Near the top of that list is the dropper post. Kid's bikes have been experiencing a bit of a renaissance lately with some terrific jumps on design. PNW is bringing its experience and expertise to the kid's market with the Fern, a dropper post just for little shredders.

Additionally, 5% of every Fern Dropper Post sold will be donated to Trips For Kids, an organization dedicated to providing access to cycling for all kids from all walks of life.



The Fern uses a lighter action cartridge to allow for little ones to actually drop the post under their own weight. With a minimum weight rating of 22-pounds, the Fern should be plenty light for the kiddos. Because it is externally routed and has a 27.2 diameter with the same cartridge construction (but operating at lower pressures) as PNW's Pine droppers, the Fern is designed to move from bike to bike as your child grows.
