FSA Flowtron Dropper Seatpost

The Flowtron is specifically designed for gravel and XC bikes with a 27.2 mm seat tube diameter. Before purchasing, ensure your frame supports internal cable routing, as this post is not compatible with external routing setups.

Yes, the clamp design is compatible with both standard 7mm round rails and oval 7x9mm carbon rails, making it versatile for various saddle choices.

The mechanical actuator allows you to tune the lever feel to your preference. You can choose from three levels of spring tension, letting you decide how much effort is required to actuate the post and how quickly it returns to the top position.

For gravel and marathon riding, 100mm is typically the sweet spot. It provides enough drop to get the saddle out of the way on technical descents without adding the excessive weight or complexity of longer-travel posts designed for enduro bikes.

The minimum insertion length is 100mm. Thanks to the integrated head design, the total insertion depth is reduced, which is helpful if your frame has a curved seat tube or limited clearance.

The Flowtron uses a sealed cartridge construction, which is designed for reliability and low maintenance. While the cartridge itself is a sealed unit, the mechanical actuator is straightforward to access if you need to adjust the return force or perform basic cable maintenance.
