31.6 Dropper Post

Dropper posts have been widely praised as the most important technological advancement to hit the mountain bike world since suspension technology. Trust us, the 31.6mm dropper is one of the best upgrades you can make to any bike that doesn’t have a dropper.

The lift bar allows the rider to sit in a comfortable position for efficient pedaling uphill. You can lower the seat for a more comfortable and stable descent with the push of a button.

Almost all mid- to high-end mountain bikes will include a dropper, while cheaper bikes may come with a fixed rigid seat post.
