Power for the people.

Bringing power measurement to their top-tier crankset, the Shimano R9100-P Dura-Ace crankarms are the essential performance tool for every cyclist who wants to achieve their true potential. 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.

The true stand-out feature is the integrated crank-based power measurement system. Offering accurate and reliable power output in real-time, the R9100-P is as useful in pre-season training as it is in the heat of the moment during a race. It boasts a completely sealed, crank-integrated design that is waterproof in all conditions. The built-in battery is recharged by a small magnetic adapter, so there is no cover to open. The direct instant response system ensures accurate data collection for stable power measurement at various stepping positions.

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