Specialized S-Works Carbon Road Crank Arms

The 2017 Specialized S-Works Carbon Road Crank Arms are a top-of-the-line road crankset. Constructed of Specialized's FACT carbon, they're light and stiff, the unusual bulge in the profile lending improved aerodynamics and high efficiency. An oversize spindle pulls the pair together into a single unit, receiving force and passing it on with nary a creak or cage rub. Compatible with both SRAM and Shimano drivetrains and available in a plethora of arm lengths for rider compatibility.
A very good road crankset.
