Pioneer Single Leg Power Meter Ultegra

Far beyond what a simple hear rate monitor can tell you, a power meter is the most valuable and necessary tool any cyclist can use to measure and quantify their efforts. Pioneer’s unique Strain-Gauge technology measures the deflection (or bending) of the crank arm to continuously quantify your riding effort.

No other cycling tool can accelerate your progress faster than working with a power meter.

Pioneer measures pedalling forces every 30˚, for 12 points of measurement per revolution. However, within those 12 points, Pioneer scans those pedalling forces an incredible 16 times, for an unbelievable 192 data points each rotation of the crank! This level of measurement is what leads to the accuracy of Pioneer power meters, as well as the basis for HDPower Metrics analysis.

The Pioneer Power Meter is built to perform in the toughest conditions. It was refined over a punishing season of racing through rain, snow, cobbles, mud and the thigh-burning climbs of the world’s most prestigious grand tours. It’s lightweight, fully integrated design adds just 64 grams to your crank, measures up to 2,150 Watts @120 RPM, and is accurate to within +/- 2%. It can be easily calibrated for varying temperatures and elevations.

  • ANT+: ANT+™ is a low-powered (2.4GHz range) wireless communications standard used by most cycle computer brands. The Pioneer Power Meter can easily pair with ANT+ compatible cycle computers and display power measurements that are available on that computer. For the full range of never-been-seen-before data including force vectors, torque vector, and other measurements, it must be paired with the Pioneer Cycle Computer.
  • Cyclo-Sphere analysis: It's the ultimate training tool. Cyclo-Sphere lets you analyse up to 199 different data points so you have comprehensive knowledge of every moment of every ride. Simply upload your ride data to Cyclo-Sphere to analyse total power, power in each leg, force vectors, torque vectors, pedalling efficiency, heart rate, speed, cadence, distance, altitude, temperature, and more. This cloud-based analysis is complimentary with your Pioneer Cycle Computer.
