Stages Cannondale Si HG Gen 3 Power Meter

The Stage Cannondale Si HG 3rd generation power meter is easy to mount and can be installed on all Cannondale BB30 Si HG or SiSL2 cranksets. The 3rd generation of Stages is 6 times stronger than its predecessor. Stages Cannondale Si HG power meter is a one-sided power meter in the left crank. It measures performance highly accurately with a minimal deviation of just 1,5%.

This power meter can use Bluetooth or ANT+ to connect to a cycling computer that measures power. In addition, you can use your phone to wirelessly perform firmware upgrades. Cadence is measured wirelessly and without the need for any extra sensors by means of the accelerometer.

The power meter only adds 20 grams to an existing crank, making it one of the lightest power meters of its kind. Owing to active temperature compensation, the measurements remain constant and accurate. This power meter is very waterproof and has an IPX7 certification. It draws power from a CR2032 battery with a battery life of around 175 hours.
