What is a Mountain Bike Dropper Post and Why Do You Need It?
A mountain bike dropper post is a type of seat post that allows the rider to lower or raise the height of the saddle on the fly while riding. This is done through the use of a hydraulic or mechanical mechanism that is controlled by a lever located near the handlebars. By allowing the saddle to be quickly and easily adjusted, a dropper post can improve a rider’s control and confidence when descending steep and technical terrain, while still delivering optimal pedaling efficiency on the climb.
