Modular Thanks to this interchangeable system, any rider or mechanic can easily, quickly, and safely swap out the spider, spindles, and chainrings from one set to another.
BB392 EVO An 92mm wide PF30 BB designed for our BB392 EVO cranksets.
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.
FSA is proud to launch the brand new KFX range, bringing a new selection of lightweight and stiff components for mountain bikes. the pinnacle of the new range is the KFX 1x crankset. The KFX modular 1x superlight aluminum 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 an advanced bonding technology. The blend of strength and stiffness gives a performance and light weight that is an ideal option for riders seeking a professional level, top of the line, crankset.
