The FSA Flowtron seatpost is compact and light and has a nice high mechanical advantage so it’s easy to actuate. FSA has also developed an adjustable actuator spring, which enables the rider to adjust how firm or light they want the lever actuation to feel.


The head is integrated into the stanchion which not only looks better, but also enables us to reduce insertion depth.


FSA presents a new diameter option in Ø27.2, mainly designed for XC and Marathon usage.


The FSA Flowtron XC dropper seatpost takes its name from a fast, rolling flow trail in the Pacific North West. A forged shifter style remote and industry first adjustable spring tension enables the rider to customize the level feel and force. The FSA Flowtron XC dropper seatpost is a "go anywhere, do anything" dropper post. Fully featured options and affordable price makes it the perfect fit for any rider’s needs.
