FSA KFX 2 Bolt mountain bike mtb carbon handlebar stem -20°

FSA KFX 2-BOLT MTB HANDLEBAR STEM

Description
FSA has always been at the forefront of XC product development, working closely with numerous professional teams. Since 2023, FSA has been the technical partner of the Cannondale Factory Racing Team, collaborating to create high-performance components tailored to the demands of elite competitions and the most demanding riders.
Guided by feedback from our partners, our engineers have developed new aluminum forging techniques, achieving production quality comparable to carbon components but at a more competitive price.

At the center of this innovation is the new 2-bolt clamp system stem design, which significantly reduces weight, increases durability, and speeds up on-site bike maintenance. Quick adjustments are essential, allowing athletes to test different setups with minimal downtime — a true marginal gain.

The -20° angle has also become a standard in competitive cycling, enabling a more aggressive, race-oriented riding position. Thanks to its specific low-profile design, the stem can be mounted on virtually any frame, even those with pronounced head tube shapes that usually prevent the use of negative-angle stems.
