Pioneer Ultegra 6800 Single Leg Power Meter
Are you using a Shimano Ultegra 6800 crankset and would like to start training with power without breaking the budget? Do you want a fast, simple installation? If you want to start training with power almost immediately, you have to get the Pioneer Single Leg Power Meter. Any ANT+ head unit that supports power will easily be synced for immediate use. Renowned electronics manufacturer Pioneer has been engaged with with cycling through the development of power measurement tools. The company has been a prominent sponsor and partner of several pro cycling teams, with the result that Pioneer's Power Meter has become highly regarded for it's accuracy, depth of data development, and overall quality. The system has been designed to be specifically integrated with Shimano's 11 speed cranksets. The Ultegra 6800 Single Leg Power Meter is a left arm only device, so you can easily swap out your existing left arm, install the power meter version, and sync to your ANT+ Garmin or other head unit. Simple and fast.
The original, two side Pioner system has strain gauges in both right and left arms of the crankset. The two leg data allows for exceptional analysis of right and left leg power output, as well as definitive understanding of the strengths and weaknesses within the pedal stroke itself. Now Pioneer is offering this more cost effective way for Shimano crank users to get started with power training with a single leg version. This is a left (non-drive) Ultegra 6800 crank arm with the power measurement device installed. You have the option of upgrading your right side crank down the road, but you get all the standard power measurement data, and the ability to sync with any ANT+ head unit for data collection.
Pioneer has it's Power Meter measure power every 30°, or twelve times every full crank revolution. The strain gauge is very sensitive device, and accuracy is within +/-2%. However, within those 12 points, Pioneer also scans those pedaling forces an incredible 16 times, for an unbelievable 192 data points each rotation of the crank. A comprehensive analysis of power throughout the stroke is possible, allowing the user to truly evaluate how to improve both power and efficiency through balancing the right/left leg effort. Pioneer offers their HD Power Metrics with Pedaling Monitor Mode when using a Pioneer head unit, which gives real time pedal stroke measurement. The data itself is collected regardless, but a private ANT connection is used with the Pioneer head unit. You still get a basic breakdown of efficiency and all standard power data options with an ANT+ head unit: power, average power, % of FTP, power within zone, training intensity, normalized power and all normal cycling stats- speed, cadence, distance, time, temp, etc.
The Single Leg unit has two accelerometers to measure and compute cadence. All you have to do to get your bike set- up is to remove your left side Dura-Ace crank arm, install the Pioneer modified arm, then sync to your head unit. The unit itself is built into the arm, and adds only 22 grams of total weight. A CR2032 battery powers the transmission for over 180 hours of use, and is easily accessible for replacement. The sensor ID is located on the crank arm, which makes pairing simple. The general set-up and zero process is straightforward and similar to other power systems. Pioneer provides excellent instructions and support. You can upload your data files via Strava, Training Peaks, etc., and Pioneer has their own free, cloud-based Cyclo-Sphere software that allows the user to really dig down in the data and allows the user to customize analysis and reporting dashboards. The program may not have the ease of today's app-based culture, but the sheer flexibility and usability of the reporting interface is actually impressive and data nerds will rejoice.
Get started quickly with this Pioneer Ultegra 6800 Single Leg Power Meter, and learn how to improve as a cyclist through power measurement. You can develop strength, leg to leg balance, pedal stroke efficiency, and learn how best to train and recover to maximize your potential for under $800. And it you decide to truly explore ultimate power measurement and analysis, you can upgrade your drive-side crank arm, and use a Pioneer GPS head unit for the ultimate real-time pedal stroke information.
