Selling this awesome rare NOS Specialized S-Works FACT "Carbon Direct Drive" road double crankset arms with 53/39 Silver alloy rings and 175mm black carbon arms.

“FACT” is Specialized technology that stands for “Functional Advanced Composite Technology”.

These are high-performance, lightweight cranks made from hollow carbon fiber, known for stiffness, featuring an oversized alloy spindle (often BB30/PF30 compatible), 110 BCD spider, and used with 10/11-speed systems.

I bought this about 10 or 12 years ago but never installed them. From what I recall they were new road bike takeoffs and appear brand new. Left arm is still inside the factory cardboard sleeve with yellow WARNING still applied.

Crankset uses the "Wave Spline technology (Hirth coupling interface spindle technology?). The original factory grease is still intact. The left arm has two tiny marks just below the “S-Works” letters (see last photo).

These specs I found online state it should be both 10 and 11 speed compatible:
