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.


  • Accurate real time data.

Great Powermeter with Shimano quality.
by Jess

I own five powermeters now...The first three were SRMs of various generations. They were all fine...until the battery needs to be replaced which even if you overnight the crankset to SRM will take them 2 weeks to change (why???). My last two powermeters have been Shimano and they're great. A little slower to register jumps in power, but great quality and best of all they're rechargeable!

The customer service at SRM was so bad (slow, unconcerned that you're without a bike while they drag their feet) that the last time I sent one in, I sent it in the Shimano box as a way of letting them know they had some competition. The Shimano is less than half the price too. I couldn't be happier!
