Pioneer Electronics ( According to a release, since its demonstration at last year's 2012 Interbike Show as an on-bike dual leg power meter and pedaling monitor system, Pioneer has been relentlessly refining the system for its North American release for superb accuracy, consistency and reliability.
Pioneer's system achieves on-bike, real time, dual-leg pedaling power measurements and analysis, graphically illustrating left and right power output, pedaling stroke efficiency, power loss, force vector analysis, and torque, in addition to cadence, heart rate, GPS positioning, speed, distance, elevation gain/loss, barometric pressure, ambient temperature, and more. At the heart of the system are two proprietary strain gauge monitors developed by Pioneer that provide the highest power recording rate (on both legs) using 12 different points (every 30 degrees) on a single 360 degree pedaling stroke. The dynamic information from the monitors is transmitted via a special ANT+ stream so it can be graphically illustrated in real time on Pioneer's customizable high-resolution cyclocomputer. Within one complete left/right stroke, up to 199 data points of the rider's performance parameters are analyzed by the system, which can be illustrated in detail on Pioneer's online service, Cyclo-Sphere.
"For the first time, riders will see a complete on-bike performance analysis of their entire pedaling stroke showing left and right leg pedaling efficiency and pedaling loss so they can instantly make changes to their riding technique in real time," said
Designed for use with Shimano DURA-ACE crank sets, Pioneer's highly accurate strain gauge monitors are designed for professional installation on both left and right arm cranks to provide detailed statistics of power, cadence and efficiency. The monitors transmit not only raw power data but also numerous parameters necessary for improving technique and performance, including where in the pedal rotation power is applied and the torque and force angle of the pedal stroke, as well as power deficiency within the stroke, which are all depicted in detail via the Cyclocomputer.
Operating time: up to 200 hours (two CR2032 batteries included)
Water resistance rating: IPX6
Resistant to oil and environmental conditions
Weight: 70g (including L & R sensors)
Accuracy: +/- 2 percent
Pioneer's Cyclocomputer provides an interface that enable riders to see their performance measurements instantly. Detailed and analyzed pedaling data, including the entire left and right force vector information, are instantly communicated to the rider on the high resolution 2.2-inch color touch screen display. The display interface is fully customizable with up to nine data points that can be seen on the screen for continuous and instantaneous performance feedback.
LCD QVGA at 320 x 240 pixel resolution
Measuring at only 3.3" x 2.67" x .86"
Built-in GPS for tracking and positioning
Barometer and thermometer
Rechargeable built-in Li-ion battery (up to 12 hours operating time)
ANT+ module to pair it with industry standard ANT+ sensors
Cadence/speed capable (component sold separately)
Mini USB cable for power charging and data transfer
