The Chorus crankset is this year available in the carbonfiber version by applying the same constructional technology as for the new Record crankset. This Multidirectional carbon fiber is a new composite materials technology recently introduced in the aerospace industry. This new technology distributes the carbon fiber in all directions to produce mechanical resistance in any direction. Layers of Unidirectional Carbon Fiber are then judiciously positioned to further enhance the already outstanding mechanical performance of the Chorus crankset.

The results are amazing:

• weighs just 515 g
• greater resistance to static load
• greater resistance to fatigue
• greater resistance to torsion

The innovative factor is that this technology has transformed a traditionally manual process like the construction of carbon-fiber cranksets into an industrial process. In this way, all the differences in terms of result and performance that are typical of the traditional manual processes have been eliminated.

This new technology also ensures uniform production quality. Another important aspect of this new carbon-fiber crankset that should be emphasized is the Q factor: it is the same as for the aluminum version.
