The Dura-Ace 7900 crank is refined in several ways. It is designed with a more flowing, aerodynamic shape and lighter weight and some great innovations setting the foundation for future trends. The hollow 3D, cold-forged outer chainring is super stiff and simply a work of art. Beyond performance, it shaves15 grams over non-3D rings. The ring is 20% stiffer which takes front shifting to a new level. In addition to lighter weight and stiffness, Shimano has optimized the tooth profile of the chainring to provide a very efficient interface with the directional 7900 chain. The tooth profile reduces friction, increases shifting performance, and allows the drive train to be virtually silent.

Taking a cue from XTR, the cosmetics features opposing anodized grey with high polished finishes. It is compatible with all Shimano Hollowtech II outboard bottom brackets. Choose crank length.
