Description 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.
Details:
4-arm Hollowtech II crankset

Adapted for race specific disc brake system
Redesigned gear teeth profile to fit wider gear pitch

Western is the best. Cranks arrived quick and they always have what I need. These cranks are so much nicer than the 8000 ultegra option. The color is super and the constriction is stiff.

As Dura Ace components go, this is as good as it gets! Light, stiff, and stylish crankset, typical of Shimano Dura Ace.
