FSA K-Force Light Carbon Crankset BB386-EVO Red 175mm 53x39FSA’s K-Force Light BB386 Crankset sheds the traditional design in favor of a new 5 arm, asymmetric design. The new design is stiffer in the highest stress point of the down stroke; you will definitely notice improved shifting and response with this upgraded system. The hollow carbon arms feature a unidirectional finish and hidden bolts and spindle for an improved look and aerodynamics. The K-Force Light weighs in at 584 grams with a BB386 spindle and includes 7075 aluminum chainrings with alloy T-30 Torx chainring bolts. It is also compatible with the new Shimano 11 speed chains. Arms are available in 170, 172.5 and 175mm lengths and in red or black graphics.400310063441
