About Pioneer Ultegra R8000 Consumer Supplied Drive Side Power Meter

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.

The Pioneer Power Meter Installation Kit comes with everything you need to package and send your existing Shimano crank to Pioneer for professional installation and calibration. Installation and delivery take approximately 7-to-10 business days.

Far beyond what a simple hear rate monitor can tell, a power meter is the most valuable and necessary tool any cyclist can use to measure and quantify their efforts. Their unique Strain-Gauge technology measures the deflection (or bending) of the crank arm to continuously quantifies your riding effort. No other cycling tool can accelerate your progress faster than working with a power meter.


12 point force measurement for high accuracy and advanced metrics - Pioneer measures pedaling forces every 30˚, for 12 points of measurement per revolution. However, within those 12 points, Pioneer scans those pedaling 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.

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.

Advanced HDPower Metrics further power and pedaling metrics analysis - Pioneer’s Cycle Computer unlocks the HDPower Metrics that allow riders to see Force Vector analysis, as well as Torque Vector and Pedaling Efficiency power metrics. These can be viewed on the Cycle Computer while riding, or in post-ride analysis using Pioneer’s free cloud-based Cyclo-Sphere software. Introduced over two years ago, these innovative features have not been matched by any of our competitors.

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.

A path for consumers to upgrade their system to a Dual Leg power meter system as they grow with their power analysis - Upgrade your analysis by adding a drive side upgrade kit, send in your existing crank to be upgraded to a Dual Leg system. There is no better, or more detailed tool for analyzing power or pedaling balance metrics than a Dual Leg system, especially when combined with Pioneer’s HDPower Metrics.

The ultimate training tools. Cyclo-Sphere for PC and supporting Cyclo-Sphere Mobile App let you analyze every moment of every ride. Simply upload your ride data to Cyclo-Sphere to view total power, power balance, force and torque vector charts, pedaling efficiency, heart rate, speed, cadence, distance, altitude, temperature, and much, much more.

Cyclo-Sphere Mobile App provides quick access to your Workout List with a powerful Segment Compare feature that allows you to choose where and when you want to challenge yourself the most. Both Cyclo-Sphere PC and Cyclo-Sphere Mobile App are complimentary with your Pioneer Cycle Computer.
