FSA KFX Drop Stem

The -20 degree angle is designed to lower your handlebar position significantly, promoting a more aggressive, aerodynamic riding posture. This helps reduce your frontal profile, which can improve efficiency and speed during intense efforts.

This stem is compatible with standard handlebars that have a 31.8 mm clamp diameter. Please verify your current bar diameter before purchasing to ensure a proper fit.

While it is engineered for speed and performance, its suitability for endurance riding depends on your flexibility and bike fit preferences. Because of the aggressive drop, it is best suited for riders who are comfortable maintaining a lower, more stretched-out position for longer periods.

The stem is built to be stiff and responsive, which creates a direct connection between your handlebars and the steerer tube. This rigidity translates into more precise steering, especially when you are sprinting or cornering hard.

Yes, you can install the stem in a positive orientation to gain a rise rather than a drop. However, it is specifically engineered for an aggressive, downward-angled setup, so flipping it may alter the intended aesthetic and handling characteristics.
