For use on the gray SkiErg manufactured July 2009–July 2014. This is the generator base and coil that transmit flywheel motion to and generate power for the Performance Monitor on your SkiErg. See more info.
If your monitor lights up with zeros, but the display does not change when you begin rowing, you may need to replace this part. If the cable or cable housing is cut or broken you will definitely need to replace this part.
