12-Point force and force direction measurement

Pioneer has created the first, and only, power meter that measures power output and pedaling stroke efficiency for each individual leg, in real time, so you can analyze and adjust your technique while you ride. At the heart of the Pioneer Power Meter System are two streamlined strain gauge monitors that can detect the slightest tangent and radial force direction as power is applied to the crank arms. This proprietary system detects the amount and the direction of force at 12 different points in each pedaling stroke for each leg.

Monitor force vectors and pedaling efficiency in real time

When used with Pioneer Cycle Computers, Pioneer has created the only Power Meter to measure force and direction of force in 12 locations – or every 30 degrees – while pedaling. When used with a Pioneer Cycle Computer, these measurements are graphically displayed as force vectors. These force vectors allow you to analyze the unique characteristics of your pedal stroke and calculate pedaling efficiency. And you can monitor it all in real-time on a Pioneer Cycle Computer, while you ride.
- Watch real time Force Vector measurement

The industry’s first accurate torque vector measurements.

When it comes to measuring torque vectors, there’s nothing approximate about it. Pioneer has designed the only Power Meter to provide precise torque vector readings at 12 points of every pedal stroke. These can be monitored in real-time on a Pioneer Cycle Computer.

Race-tested, rider-perfected

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 and is available in red and black transmitter caps.

Compatible with ANT+ Cycle Computers

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.

Post-ride data like you’ve never seen before

It's the ultimate training tool. Cyclo-Sphere lets you analyze 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 analyze total power, power in each leg, force vectors, torque vectors, pedaling efficiency, heart rate, speed, cadence, distance, altitude, temperature, and more. This cloud-based analysis is complimentary with your Pioneer Cycle Computer.
