FSA SL-K Seatpost

This seatpost has a diameter of 27.2 mm. You must verify your current seatpost diameter or check your frame manufacturer's specifications to ensure compatibility, as this is a standard size but not universal.

A zero-setback design means the saddle clamp is positioned directly in line with the seatpost tube. This typically pushes your saddle further forward, which can help you achieve a more aggressive, forward-leaning position for efficient power transfer.

The FSA SL-K features a standard railed clamp design. While it works with most traditional railed saddles, you should check the specific clamp requirements of your saddle, especially if it uses oversized carbon rails, as some clamp designs require specific adapters.

The minimum insertion length for this seatpost is 100 mm. Always ensure the post is inserted at least this far into your frame to prevent damage to both the seatpost and the frame's seat tube.

Yes, the hybrid construction is designed to balance the vibration-damping properties of carbon fiber with the structural reliability of aluminum. It offers a stiffer, more direct feel than an all-carbon post while maintaining a competitive weight of 226 grams.
