About Pioneer Dura-Ace R9100 Left Crank Power Meter

Pioneer’s most affordable step into power measurement

Far beyond what a simple heart 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.

Features

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.


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.


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.

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.
