Dura Ace FC-R9100-P 11-speed Crank Arms with Power Meter
With Shimano?s first integrated power meter you can expect extremely accurate real time power data to track and analyze your performance.
Most advanced component group of all time: Shimano Dura Ace FC-R9100-P 2×11-speed Crank Arms with Power Meter The power meter allows integration and easy installation (pairing) with third party display units to enable the most sophisticated and accurate level of performance measurement and anatomic analysis available today. Not only can the pure output of watts be measured, left and right legs can be measured separately, as well as cadence, giving you the truest measure of performance, isolated from external factors such as gradient, road surface and wind.
The FC-R9100-P is Shimano?s first pedaling power measurement product and also the first crank-integrated power meter on the market. It is built to provide riders with one of the most accurate systems of power measurement, utilizing technology from bikefitting.com, a Shimano-owned company specializing in highly advanced bike fitting and bike measuring instruments.
With the introduction of DURA-ACE R9100, Shimano has reestablished the new benchmark for road performance by improving each component and incorporating its newest digital technologies. DURA-ACE R9100 delivers unparalleled performance, highly-refined ergonomics and immense customization to maximize every rider?s potential.
Engineered for the next generation of race bike, DURA-ACE R9100 offers top-tier performance across numerous configurations. Available with either Di2 electronic or mechanical shifting, for the first time, riders now have the option of premium DURA-ACE hydraulic disc brake performance. New Shimano technologies further integrate the DURA-ACE as a system, including a new power meter, while riders further integrate with their bike through new E-Tube wireless connectivity. Shimano?s Rider Tuned philosophy and customization of the bicycle?s function also expands with a wider range drivetrain that now includes intuitive Shimano Synchro Shift control.

Technologies Power Meter? The power meter ?brain? sits inside the Dura Ace drive crank body (the spider) and the strain gauges sit inside the crank arms to measure left and right leg power. The brain is discrete and compact, providing a system that?s one of the lightest and cleanest on the market. Because the power meter is connected to the spider, chain rings can be easily changed without affecting the power meter?s accuracy. The system checking and firmware upload can also be operated by your smart phone or tablet PC through a Bluetooth connection (E-TUBE). An integrated rechargeable battery powers the unit. This can be charged with a small magnetic adapter without needing to remove covers or casings.
HOLLOWGLIDE – Hollow technology on outer chainring? High rigidity hollow structure cuts down on weight yet maintains strength. Better power transfer and quicker and more precise front shifting.
HOLLOWTECH II – Providing the best balance of stiffness, strength, weight and rotating performance The concept of HOLLOWTECH II technology is focused on producing a superior crankset which will maximize a rider?s power transfer. The rigidity of the crankset ensures pedaling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. Naturally, SHIMANO strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the company?s own proprietary forging technology that also maintains rigidity. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crankarm for more stiffness and a weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling stability, allowing for more efficient power transfer. Shimano DURA-ACE R9100 (Di2)
