Stages Hollowgram Si HG Power Meter

Power meters are here to stay, and the Stages Power Meter is set on revolutionizing the power meter game. It comes factory installed on your left crank arm of choice and is no heavier than an energy gel, making it lighter than most power meters available. The installation process is as simple as switching out the left crank arm, because of this, you can run it on multiple bikes. The battery life lasts up to 200+hours, and when needed can be swapped out tool-free, making the process fast and easy.

The Stages Hollowgram Si HG Power Meter is compatible with Ant+ and is Bluetooth Smart ready, allowing true two-way communication between the Stages Power Meter and a smartphone or Bluetooth enabled head unit. Your cadence is measured through an accelerometer based measurement with a range from 20-220 rpm. Since there are no moving parts and it features a water proof housing, the Stages Power Meter can handle all weather conditions and any riding style.
