Users will still need a Pioneer head unit to take advantage of the HD metrics, but can use an Ant+ bike computer for basic metrics. The single-arm version is reported to add only 22 grams to the weight of the crank arm and will provide all the same metrics of their dual-leg system, except for metrics that require dual-leg data such as left/right power and pedaling balance. It also gives the user the ability to adjust the estimated total power based on any pedaling imbalances so that total power estimated will provide a more accurate representation.

The Pioneer single-arm power meter weighs in at just at 22 grams.

Hidden behind the non-drive side crank, the power meter looks very subtle.
