Stages 105 5800 Gen 2 Power Meter

The Stages 105 5800 power meter is integrated into the left crank arm. The easy installation makes it highly user friendly. All you have to do is replace your current left crank arm with the Stages 105 5800, pair it to your cycling computer, perform a one-time calibration and off you go. The crank is fitted with an internal accelerometer which can provide you with your current cadence without needing a magnet. The Stages crank arm only adds 20 grams over the regular Shimano 5800 crank arm. This makes the Stages one of the lightest power meters on the market, and all that at a highly competitive price.

The Stages 5800 can be paired using both ANT+ and Bluetooth Smart. The app on your phone enables you to keep your Stages power meter updated with the latest firmware. The Stages power meter is highly accurate (just a ±2% deviation) which has earned it nothing but high praise.

Important notice: please make sure whether the power meter is compatible with your direct mount bottom bracket brake, should you have one.
