FSA K-Force OS-99 CSI Stem - UD Carbon/black

The OS-99 CSI stem in fresh K-Force design. It is an elaborate manufactured stem with CSI UD carbon cover! CSI (Carbon Structural Integration) is a process that permanently bonds carbon to aluminium, to create a true hybrid product, with many of the benefits of aluminum and Carbon. The OS-99 is 3-D forged and CNC machined from AL2014 before a UD carbon weave skin applied through CSI process. To further reduce weight the OS-99 uses a 4 bolt sculpted AL2014 aluminium/carbon faceplate and titanium screws.
