Dropper post
Every bike should have a dropper post, and this one does. A dropper post is a must-have these days if you’re riding anything remotely technical. The main benefit of a dropper post is increased safety while riding. As mentioned above, the lever system allows you to quickly move the saddle out of the way when approaching descents or trail obstacles.
