FSA’s flagship road chainset features hollow carbon fiber arms for amazing stiffness and low weight. The adaptable BB386EVO 30mm spindle will fit a wide variety of frames with a range of BB standards. The K-Force Light uses FSA’s Asymmetric Bolt Standard, with four bolts at 90 degrees to one another and a fifth behind the crankarm, adding support where it’s needed. Choose from the traditional 53/39 chainring combination, 50/34 compact or 52/36 semi-compact. The unidirectional carbon finish, updated graphics and concealed chainring bolts make the K-Force Light look as fast as it is.
