FSA K-Force OS-99 CSI 6° stem with carbon finish

The FSA K-Force OS-99 CSI stem features a 3D forged and CNC-machined AL2014 structure. A layer of unidirectional carbon is added using the Carbon Structural Integration (CSI) system. This process bonds carbon and aluminium to create a hybrid product that offers the advantages of both materials. Every detail has been carefully considered, such as the use of aluminium screws to attach the handlebar, a carbon stem cap, and two titanium screws to tighten the pivot, resulting in a high-end stem with a low weight.span>
