FSA OS-99 CSI Road Stem
The FSA OS-99 is part of FSA's K-Force series. 3-D forged and CNC machined from 2014 Aluminum, (the same stuff used in the aerospace industry), this stem is constructed for precision to bring the ultimate in shaved weight stem design. A unidirectional carbon weave skin is then applied through FSA's Carbon Structural Integration process, for increased stiffness and an awesome looking carbon aesthetic. To further reduce weight, the OS-99 uses a 4-bolt sculpted AL2014 all-carbon faceplate and titanium hardware. With both the benefits of aluminum and carbon, the OS-99 is a truly amazing hybrid stem that's lightweight and highly durable with plenty of precision and control on the road.
