FSA has produced a matching quality aluminum crank arm exclusively for SRM. The FSA Gossamer crank arm is made of 6061-T6 Cold Forged aluminum, which yields a higher stiffness than its carbon cousin the K-Force Light, with only a modest weight penalty. The SRM FSA Gossamer Standard PowerMeter has become the SRM’s most affordable PowerMeter model, while still maintaining SRM’s accuracy and durability.
