Stages power is now available on Shimano's newest R8100 series groupset. The Stages Cycling Ultegra R8100 Power Meter replaces your current left-side crank arm. Like all Stages power meters, this unit features +/- 1.5% accuracy, 200 hours of battery life, and is lightweight at only 15 grams of added weight. 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.
