Stages Shimano 105 5800 Power Meter
Compatible with all Shimano Hollowtech II road cranks, the Stages Shimano 105 5800 Power Meter replaces your current left-side crank arm. Like all Stages power meters, this unit features +/- 2.0% accuracy, 200 hours of battery life and is lightweight at only 20 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 new versions also feature improved accuracy (+/- 1.5%) and have an LED indicator light on the housing for improved ease of use.
Crank arm lengths: 165 mm | 170 mm | 172.5 mm | 175 mm
