Titanium offers a reduction in weight compared to steel, while guaranteeing excellent resistance.


Carbon Structural Integration (CSI) is a fusion of carbon fiber and aluminum. A structural outer layer of carbon fiber is wrapped around a component's aluminum core to increase the part's stiffness and create an elegant carbon aesthtetic.


The new KFX range brings a new selection of lightweight and stiff components for mountain bikes.

The KFX Stem is 3D forged and CNC-machined from AL2014 alloy. Then it’s combined with a carbon structure using FSA CSI (Carbon Structural Integration) technology. 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. Riders have the option to run this stem at + or -12° to suit their riding style. For those whom a 20° drop is too much, a slightly less aggressive lightweight option is also available.
