FSA SL-K Stem

The aggressive -20 degree drop is designed to lower your handlebar position significantly. This helps you achieve a more aerodynamic, race-oriented posture, which is ideal for time trials or riders looking to get lower over the front end for better handling.

This stem is compatible with standard 1-1/8 inch steerer tubes and 31.8 mm diameter handlebars, which covers the vast majority of modern mountain and road bikes. As long as your current setup uses these standard dimensions, it will be a direct fit.

Cold-forging the AL-2014 alloy aligns the grain structure of the metal, resulting in a stem that is both exceptionally stiff and lightweight. This ensures that your steering inputs remain precise and responsive, even when you are putting down high power during sprints or technical riding.

The stack height is 40 mm. This measurement is important because it dictates how much space the stem takes up on your steerer tube; you need to ensure you have enough steerer tube length available to accommodate this height, or you may need to adjust your headset spacers.

Yes, the SL-K stem is built for durability and stiffness, making it well-suited for demanding disciplines. Its robust construction and reliable CrMo hardware provide the security needed for technical terrain, though its geometry is specifically optimized for riders seeking a lower, more aggressive cockpit.
