The FSA K-Force OS-99 CSI stem is 3D forged and CNC machined from 2014 aluminium. It combines a carbon structure using CSI (Carbon Structural Integration) technology. CSI is a process that permanently bonds carbon and alloy to create a true hybrid product with the many advantages of both aluminium and carbon. The final details reduce the weight of the OS-99 stem by using a sculpted AL2014 alloy/carbon face plate with 4 nuts and titanium bolts.
