FSA K-Force Light OS-99 Carbon StemFor the K-Force Light OS-99 Carbon, FSA has taken their lightweight aluminum OS-99 and wrapped it in a beautiful carbon 3k weave. The 3k weave is bonded to a 3D forged aluminum sub structure for a stem that is stiffer and more durable with only a slight weight penalty. The FSA K-Force Light OS-99 Carbon stem is an excellent choice for the powerful rider that wants a very stiff front end, or for that rider who appreciates the look of carbon in all the right places.
