Pioneer Shimano DURA-ACE 9100 Power Meter

Featuring Pioneer’s 12-point force measurement technology, the Pioneer Shimano DURA-ACE 9100 Power Meter comes ready to ride on a Shimano 9100 left crank arm. Known for their accuracy and advanced data metrics, Pioneer power meters can measure your pedaling forces every 30 degrees, for 12 points of measurement per pedal revolution. When paired with a Pioneer Cycle Computer (optional), you get access to Pioneer’s HDPower Metrics. These metrics include Force Vector, Torque Vector and Pedaling Efficiency analysis.

The Pioneer 9100 Power Meter runs off an easy to change CR2032 battery and gets approximately 180 hours of battery life. The unit is lightweight, adding only 22 grams to the weight of the crank arm and it is both IP66 and IP68 water resistance certified. In addition, the power meter is both ANT+ and Bluetooth SMART compatible and can be used with the Pioneer Cycle Computer or your favorite head unit.
