FSA KFX Drop Stem

The -20 degree drop is designed to help you achieve a more aggressive, aerodynamic riding position. By lowering your front end, it reduces your frontal profile, which can improve efficiency during fast road rides or gravel races.

This stem is compatible with handlebars that have a 31.8 mm clamp diameter, which is the industry standard for most modern road and gravel bikes. If you are unsure of your current bar size, check the center section of your handlebars for a printed specification.

It is perfectly suited for both. The durable, CNC-machined alloy construction provides the stiffness needed for road sprinting while offering the reliability required to handle the vibrations and varied terrain of gravel riding.

Like any high-performance component, you should tighten the four bolts in an 'X' pattern to ensure even pressure distribution across the faceplate. We recommend using a torque wrench to meet the manufacturer's specified torque settings to prevent damage to your handlebars.

While carbon stems can offer slightly more vibration damping, this alloy KFX stem provides exceptional stiffness-to-weight performance at a more accessible price point. It is a robust, reliable choice if you prioritize responsive handling and durability over the marginal weight savings of carbon.
