  • FSA KFX CK-9011/IS ARMSET

    Lightweight
    The new KFX range brings a new selection of lightweight and stiff components to e-mountain bikes.

    Revolutionary manufacturing process
    Each KFX crank arm starts out as two separate forged blanks. Then precision CNC machined into two pieces, the hollowed-out halves feature a series of three main ridges & grooves down the outside of each arm that form a tightly interlocking single piece.

    The KFX superlight aluminum E-MTB crankset is created through an innovative manufacturing process that dramatically reduces weight while increasing stiffness. The hollow construction begins with forging, then precision CNC machining, and finally culminating with advanced bonding technology. The blend of strength and stiffness gives a performance and lightweight that is an ideal option for riders seeking a professional level, top of the line, crankset.
