FSA KFX Stem

The hybrid construction uses CSI (Carbon Structural Integration) technology to bond carbon fiber to an alloy core. This gives you the high stiffness of aluminum for precise steering while utilizing carbon to dampen trail vibrations and reduce overall weight.

This stem is designed for a 31.8mm handlebar clamp diameter and a standard threadless steerer tube. Please verify your current handlebar diameter and steerer tube size before purchasing, as it is not compatible with 35mm bars or tapered steerers that require specific stem geometry.

The -12 degree angle provides a more aggressive, lower front-end position compared to standard stems. This is ideal for cross-country riders looking to keep their weight over the front wheel for better climbing traction and precise handling.

Yes, the stem features a removable four-bolt faceplate. This makes it straightforward to swap out handlebars without having to remove your grips, shifters, or brake levers.

While the KFX is built for rigorous trail and cross-country use, it is optimized for weight savings and stiffness rather than heavy-duty gravity riding. If you are frequently riding lift-access downhill or extreme enduro terrain, you may want to consider a stem specifically engineered for those higher-impact disciplines.
