For many riders, the dropper post is the most important innovation in modern mountain biking. Dropper posts give you more freedom of movement when riding, which is especially useful on technical trails and steep descents, because you can move your centre of gravity backwards for increased stability. Straight away, you’ll be able to do trails that seemed too intimidating before. You’ll descend with more confidence. You’ll ride better. Once you switch to a dropper, you’ll never want to go back. Guaranteed. The TranzX +RAD dropper post is easy to use: simply press the handlebar-mounted switch (not included) and sit on the saddle to drop it down to whatever height you want. You don’t have to stop riding to make adjustments – saving time and never breaking your feeling of flow. And when it’s time to climb, just stand up and push the switch again to raise the saddle back up.  Adjustable travel: In contrast to regular dropper posts the +RAD uses a unique integrated collar system that enables the rider to adjust the travel of the seatpost whenever, wherever! Thanks to a stepped travel bushing, no tools are needed to change the dropper’s travel. Simply lower the post, remove the mid cap, reset the travel bushing, and reinstall the cap. Each post has a maximum travel adjustment range of -30mm in 5mm increments.
