Pioneer Shimano Ultegra R8000 Power Meter

The Pioneer Shimano Ultegra R8000 Power Meter comes ready to ride on a Shimano R8000 left crank arm. Featuring Pioneer’s 12-point force measurement for high accuracy and advanced metrics, it can measure pedaling forces every 30 degrees, for 12 points of measurement per pedal revolution. This level of measurement is unique to Pioneer power meters. In addition, when paired with a Pioneer Cycle Computer, you get access to Pioneer’s HDPower Metrics including Force Vector analysis, Torque Vector and Pedaling Efficiency power metrics.

The Pioneer R8000 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 IPX6 and IPX7 water resistance certified. The power meter is ANT+ compatible and can be used with the Pioneer Cycle Computer or your favorite ANT+ head unit.

Installation takes about 10 minutes and simply involves swapping your current left-side crank arm for your new, power-equipped version. The Pioneer R8000 Power Meter is also easily upgradable. At any point, you can purchase and upgrade kit for your drive side crank arm and turn your Pioneer into a complete, dual-sided system.

  1. Rated 5 out of 5


    The absolute best upgrade ever. I have used this power meter since January. Since then, no ride has been meaningless and the Pioneer PM has made me many PRs and KOMs. If I make more money, I will order the right side PM additionally.
