FSA Afterburner Stem

Yes, the Afterburner is specifically engineered for mountain biking and technical trail riding. Its forged aluminum construction is designed to handle the stresses of aggressive terrain while maintaining a lightweight profile.

This stem is compatible with handlebars that have a 31.8 mm clamp diameter, which is a standard size for most modern mountain bikes. Please verify your handlebar diameter before purchasing to ensure a proper fit.

This stem features a 12-degree angle. Depending on how you orient it, you can use this to either raise your handlebar height for a more upright position or flip it for a lower, more aggressive stance.

Yes, it is designed for a standard 1-1/8 inch threadless steerer tube, which is the most common size found on modern mountain bike forks.

Forging aligns the grain structure of the aluminum, resulting in a stronger, more durable component that can withstand the high-impact forces of trail riding. It allows for a lighter overall weight without sacrificing the structural integrity needed for precise steering.
