FSA OS-99 CSI UD Carbon V14 Ahead Stem - Black, 90 mm

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.Features:- 3D forged and CNC machined from AL2014- UD carbon weave skin applied through CSI process- 41mm fork clamp stack height- Finish UD carbon finishSpecifications:- Weight 126 grams (100mm)- Sizes:+/- 6º x L80, 90, 100, 110, 120, 130mm- Diameter 31.8mm handlebar clamp- 41mm fork clamp stack height
