Shimano Ultegra 6800 Powermeter Crankset

After teaming up with Belkin's professional cycling team for extensive testing, Pioneer created its latest power meter design to ensure the best possible performance through punishing conditions. The re-engineered Pioneer Shimano Ultegra 6800 Power Meter Crankset is compatible with ANT+ cycling computers, pairing with Pioneer's SGX-CA900 and 500 cycling computers for real-time monitoring of torque vectors (Pioneer computers only) and other performance-savvy metrics. It even uploads data via Wi-Fi to Pioneer's CycloSphere, which is a free, cloud-based service for post-ride analysis of riding statistics.

The cranks themselves are fitted with a left and right strain gauge for force measurement at 12 points every 30-degrees throughout each pedal rotation. Measuring the smallest of details, the sensors relay data to a transmitter bolted directly to the crank's spider for a sleek, low-profile design. Displaying data in real time, power magnitude, power direction, and pedaling efficiency are delivered to your cycling computer for analysis as you train.

The Shimano 6800 cranks benefit from trickled-down technology from Dura-Ace 9000, notably its Hollowtech II construction for reduced weight without sacrificing stiffness. Additionally, its four-arm spider further contributes to its low weight and high levels of stiffness.
