FSA KFX Drop Stem

The aggressive -20 degree drop allows you to achieve a much lower, more aerodynamic riding position. It is specifically designed for riders who want to optimize their bike fit for competitive road or gravel racing.

This stem is compatible with standard 1-1/8 inch steerer tubes and 31.8 mm handlebars, which are the most common sizes for modern road and gravel bikes. Always double-check your current bike's specifications to ensure compatibility.

Yes, it is an excellent choice for gravel racing. The aggressive geometry helps you maintain a lower profile, while the stiff construction ensures precise handling when navigating technical terrain or sprinting.

FSA engineered this stem with a focus on material optimization, stripping away excess weight without compromising structural integrity. This results in a component that feels responsive and rigid during high-power efforts like climbing or sprinting.

A 90mm length is a versatile mid-range size that offers a balance between stability and quick, responsive steering. If you are switching from a different length, keep in mind that it will slightly alter your reach and how the bike feels in corners.
