Strong arm.

The stretched width of the R9100 Dura-Ace crankset is instantly noticeable and indicates that Shimano's flagship drivetrain means business is serious as usual. Its design is the result of stress-test data, resulting in increased stiffness that's 7 g lighter overall compared to the previous generation Dura-Ace crank. Hollow construction technologies are still prominent, including 4-arm Hollowtech II arms and Hollowglide chainrings in a variety of rider-tuned gearing options. Re-positioning of the inner chainring and altered tooth profiling ensures superior performance with modern short-stay geometries, 135 mm rear-spaced frames, and wider-range cassettes.

Available in multiple crank lengths and gearing options. Compatible with Shimano BB-R9100 and BB-R9100-PB bottom brackets.


  • 4-arm Hollowtech II crankset
  • Hollowglide chainrings
  • Adapted for race specific disc brake system
  • Redesigned gear teeth profile to fit wider gear pitch
  • Rider tuned gearing options
  • Chainline: 43.5 mm
