A Look at the DURA-ACE R9100-P Power Meter

The DURA-ACE FC-R9100-P power meter: the essential performance tool for every cyclist who wants to achieve their true potential.


With the first integrated power meter, you can expect extremely accurate data. The FC-R9100-P is Shimano’s first power meter, as well as Shimano’s first crank-integrated power meter on the market. It retains its unique asymmetrical four-arm spider construction, but with a ‘brain’ mounted on the inside. On its crank arm are the strain gauges. Working perfectly in sync with each other, you can use the extremely precise power data to improve your performance.


By gathering real-time accurate and reliable power output data, you can track and analyse every detail of your ride. You can then use this potent information to tune your training and racing for maximum results.


Power meters are one of the fastest growing technologies in cycling. In just a few years, they have moved from being pro-only equipment to affordable training aids for amateur racers and keen recreational riders.  



Crank Integrated

The Shimano FC-R9100-P power meter guarantees reliability. 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.

Plus a simple reset by a switch on the transmitter.
