The K-Force OS-99 CSI stem is 3D forged and CNC machined from AL2014. It is combined with a carbon structure using CSI (Carbon Structural Integration) technology. The CSI process bonds carbon to alloy to create a true hybrid product, with many of the benefits of aluminum and carbon. The final details reduce the weight of the OS-99 stem by using a 4-bolt sculpted AL2014 alloy/carbon faceplate and titanium hardware.
These stems have been used a few times but got some scratches
