FSA brand components and accessories are now available at Escapa. The FSA OS-99 Carbon 31.8 Stem is 3-D forged and CNC-machined from AL2014. It is then combined with a carbon structure using our CSI (Carbon Structural Integration) technology. CSI is a process that permanently bonds carbon to the alloy to create a true hybrid product, offering many of the benefits of both aluminum and carbon. The final details reduce the weight of the OS-99 stems by using a sculpted 4-bolt AL2014 alloy/carbon plate and titanium hardware.
