Stages Power Meter G2 SI HG Crank

The Stages Power Meter G2 SI HG Crank is the power meter option for all Cannondale BB30 riders who are on a Cannondale Si HG crankset. The G2 SI is pre-assembled on a Si HG left crankarm and will also retrofit to SISL2 cranks. It replaces the existing left crankarm which makes installation pretty simple, due to the left crankarm interface there is no interference with the drivetrain components. This power meter uses a custom strain gage array to measure power at the left arm. By measuring power here, Stages Power eliminates the complexity of filtering the power data from chain torques and the multiple vectors associated with spider based units or efficiency losses through the drivetrain. This measurement then derives total power using an algorithm that effectively doubles a rider’s left-measured power. The Stages Power is compatible with all ANT+ cycling computers as well as with the latest smartphone models via ANT+ and Bluetooth Smart technologies.
