When you are mountain biking, you need to be able to quickly shift your body weight from one side to the other, to the back, or to the front, depending on the conditions. An adjustable seat post makes that job so much easier because it allows you to lower and raise the height of the seat by simply maneuvering a lever, just like you would an office chair. When you push the lever and apply weight to the seat, the saddle will lower. Push the lever once more while taking your weight off the saddle and the seat will come back up. The lever is usually located on the handlebar or even on the seat post itself.
While more and more adult riders have become familiar with the system and use dropper posts all the time, there aren’t so many great options for kids. PNW Components recently launched the Fern kids post, which makes riding so much more fun for the little ones.
The Fern was designed specifically for young riders, in a way that allows them to drop the saddle without any effort. It has a cartridge that can operate at really low pressures, which means much less weight is required to lower the saddle. The cartridge supports riders with weights ranging from 44 to 110 lb (20 to 50 kg).
With a 90 mm (3.5 in) travel and a 27.2 mm (1.07 in) diameter, the Fern dropper weighs 500 grams (17 oz) and is made of 7075 aluminum alloy. While it doesn’t include the lever, it is compatible with all the PNW levers and most cable-actuated levers from other brands as well.
The Fern dropper post is designed for any weather conditions and fits a variety of bikes, even as your kid gets older.
You can order the Fern for $200.
