FSA Road OS-99 Carbon 31.8 -100 stem

The K-Force OS-99 csi is 3-D forged and CNC machined from AL2014 before a uni-directional (UD) carbon weave skin applied through the Carbon Structural Integration (CSI) process. To further reduce weight the OS-99 uses a 4-bolt sculpted AL2014 alloy/carbon faceplate and titanium hardware. CSI is a process that permanently bonds carbon to alloy, to create a true hybrid product, with many of the benefits of aluminum and carbon.
