The KFX stem is 3D forged and CNC machined from AL2014 alloy. It is then combined with a carbon structure using FSA's CSI (Carbon Structural Integration) technology. CSI is a process that permanently bonds carbon to alloy, creating a true hybrid product with many of the advantages of both aluminum and carbon. Riders have the option to run this stem at + or -12° to suit their riding style. For those for whom a 20° drop is too much, a slightly less aggressive lightweight option is also available.

  • 3D forged and CNC machined AL2014
  • Carbon Structural Integration (CSI)
  • Titanium hardware
  • 31.8 clamp diameter
  • 35mm clamp stack height
  • Weight: 143g (100mm)
