Crank Brothers Seatposts

Crank Brothers Joplin Seatposts offer a hydraulic action that allows you to instantly fine tune your seat height, and therefore your riding position, while riding.

Combining 4 inches (100mm) of infinitely adjustable vertical height adjustment, with your choice of either sleek minimalist lever operation or super ergonomic remote operation you'll never have to stop at the top of a trail with a pile of allen keys again.
