Shimano dura-ace fc-r9100-p hollowtech ii power meter cranks w o chainrings

Product Description The Dura-Ace FC-R9100-P Power Meter Crankset by Shimano - Real-Time Power Measurement Shimano presents its first-ever power meter - the Dura-Ace FC-R9100-P crankset. This crankset was developed in collaboration with bikefitting.com, Shimano's sister company specialising in bike ergonomics. Power is measured using the crank arm from both the left and right sides. The cadence and other important values for training, such as smooth pedal strokes, are also part of the power meter's range of functions. It can be paired with bike computers enabled with ANT+ or Bluetooth. The FC-R9100-P cranks harness real-time power measuring and recording, and can aggregate and assess measurement data. Just like „normale“ FC-R9100 without power measuring, the Power Meter crankset is a hollowtech crankset with hollow forged aluminium arms and Hollowtech II construction for an optimum stiffness-to-weight ratio. The chainstays in the present version are not included. Only the chainring bolts are included.

It is based on an integration of the bottom bracket and the right crank arm and works with a 24 mm axle or bearing diameter, which has proven to be optimal in terms of stability. In many cases, the bearing cups are on the outside so that the load is better distributed. High-quality precision seals ensure a long service life. First-Generation Power Meters Shimano first-generation power meters operate with a central power meter on the crankcase, positioned inconspicuously behind the chainrings. Strain gauges are installed in the crank arms, which record the power for the left and right sides separately. The power meters have Bluetooth and ANT+ compatibility to communicate with bike computers and smartphones. You can easily recharge the integrated battery via a magnetic adapter.
