FSA

K-Force Seatpost SB25

If you were to ask us what we want in a seatpost, we would have 2 requests. One, it's made of carbon fiber so its lightweight and help dampen vibrations. Two, it has a 2 bolt head for easy saddle install, adjustments, and when clamped, it stays put. FSA's K-Force Seatpost SB25 ticks off both of those boxes and as a plus, it's a very sleek design that looks great on any bike.

The K-Force line of components from FSA is its top-tier model and used by the many of the WorldTour teams it sponsors. Pro riders demand strength, stiffness, and lightweight and the use of unidirectional carbon fiber allows for this while allowing the post to quell some road noise. The alloy Minimal Top Clamp and twin bolt design allow for a wide range of adjustments in both tilt and fore-and-aft while supplying a vise-like grip on the rails so your saddle doesn't move.

The FSA K-Force post is available in 31.6 and 27.2mm diameters and 400mm in length. Shimano Di2 battery can be housed in the bottom of the post if used with the battery plug.
