Bilateral Stages Power On An Ultegra 8100 Platform
Stages power is now available on Shimano's newest FC-8100 series groupset. The Stages Cycling Ultegra FC-R8100 Power Meter replaces your Ultegra 8100 series crankset, providing balanced, left and right-specific dual-sensor bilateral power measurement and data tracking. Like all Stages power meters, this unit features +/- 1.5% accuracy, 200 hours of battery life and is extremely lightweight. In addition, the power meter is compatible with both ANT+ and Bluetooth SMART devices. This means you can use a bicycle computer with ANT+ or your smartphone or tablet with Bluetooth SMART.
The new Stages Generation 3 power meter features radio antennas that are 6x more powerful than the previous version. This means better compatibility with both bike computers and watches. The Gen 3 also features improved accuracy and has an LED indicator light on the housing for improved ease of use.
