FSA has always been committed to developing new technologies for their products. Over the past 2 years, FSA engineers and designers have revolutionized the next generation of the K-Force Light cranksets.
The K-Force Light crankset has always had all the features necessary to win races and impress those who ride them. Those features include light weight, high stiffness and direct power transfer.
Although previous designs of this model crankset have won numerous podiums at the highest level of racing, FSA engineers were still not satisfied.
The goal was to increase stiffness, optimize shifting precision, and decrease weight. The solution was a total change in the design of the product in order to reach these goals.
FSA Engineers knew that the power applied through a 360 rotation is not constant. The load peaks when the leading crank-arm is horizontal. For this reason, FSA engineers added a 5 bolt asymmetric spider (with one bolt hidden behind the crank arm) putting more chainring bolts where the stress is highest. In addition, newly designed 3D forged ABS chainrings have optimized teeth profiles and shift ramps which result in faster, smoother, and more precise shifting.
This new configuration allows an increase in the stiffness of the crankset, giving huge benefits to both riding and shifting.
The hidden bolts and a masked spindle result in clean, elegant, and aerodynamically efficient surface.
