Pioneer Power Meters Offer Single Leg Option with Shimano 105 Compatibility


Pioneer announced today, the expansion of its line of power meters with the introduction of a new Single Leg power meter designed to offer a more affordable option for road and cyclocross riders alike. 

Compatible with Shimano Dura-Ace, Ultegra 6800 and 105 cranks, the new Single Leg power meter has become what Pioneer says, “is the most affordable step into power meters offered by any company.”

Power meters have quickly become the most accurate means a cyclist can use to evaluate performance data. As result, crank-based power meters have become a mainstay with not only professional cyclists, but amateur and multi-sport riders as well. With Pioneer’s introduction of its Single Leg power meter, integrating power metrics into one’s cycling regimen, has moved even closer within the reach of every cyclist.  

“Weekend warriors and non-professional level riders typically use a heart rate monitor to judge effort, but they’re now demanding a more accurate way to monitor and improve on-bike performance for a better ride,” said Russ Johnston, executive vice president of marketing and corporate communications for Pioneer Electronics . “Power isn’t exclusive to professional cyclists and triathletes. We want riders of any level to utilize power metrics to define their own victories. Our new Single Leg Power Meter is a great starting point for any rider interested in incorporating power and power metrics to develop and ride their personal best. What makes Pioneer unique in the industry is the ability for the rider to grow with the system and eventually upgrade to our advanced Dual Leg Power Meter when they want more power metrics.”

Just as Pioneer’s Dual Leg power meter, the new Single Leg utilizes strain gauges located on the crank arm to measure deflection caused by pedaling force on the arm. Power data is therefore measured every 30 degrees, 12 times per crank rotation. Using a crank-based power meter measures closest to the source of the force to provide better power measurement accuracy. Additionally, two accelerometers provide precision, cadence and advanced error correction for the most accurate cadence and power analysis. The ANT+ Single Leg Power Meter is compatible with ANT+ devices, including ANT+ sport watches. Riders with ANT+ computers will be able to see all ANT+ power metrics supported by that computer.


HDPower Metrics

The Single Leg meter can also be used in conjunction with Pioneer’s SGX-CA900 or SGX-CA500 cycle computer, which in turn can provide unprecedented in-depth power data and analysis. Moreover, adding one of Pioneer’s cycle computers to the Single Leg power meter enables cyclists to see comprehensive performance analysis and highly detailed data, gathered from 12 points of measurement, displayed graphically in real-time, including Force Vector and Torque Vector graphics and pedaling efficiency.

“We’re excited to be working with the recently debuted Maxxis-Shimano Professional Cyclocross Team as a technological partner for our new product,” said Johnston. “The talented Maxxis-Shimano team will be riding our Single Leg Power Meter system in the upcoming cyclocross season that kicks off at the CrossVegas World Cup on September 16.”

Cyclists also have access to post-ride analysis via Pioneer’s free on-line cloud service called, Cycle-Sphere, which offers a comprehensive and detailed breakdown of ride data. With Cyclo-Sphere, more than 200 performance metrics are collected by the system and illustrated in detail utilizing a variety of graphs, charts and maps. Furthermore, the SGX-CA500’s built-in Wi-Fi allows for automatic uploads of collected ride data into Cyclo-Sphere, STRAVA and TrainingPeaks.

Upgrade Path

According to Pioneer, the new Single Leg Power Meter is adaptable and grows with the user. To wit:

“As riders’ power needs develop, Pioneer offers an upgrade path to the Dual Leg Power Meter system used by professionals. Transitioning from 12 points of measurement to 24 points of measurement, the Dual Leg Power Meter system offers the most accurate total power measurement and pedaling balance metrics critical to analyze ride performance and reveal opportunities for ride improvement. The Single Leg Power Meter is an affordable starting point for cyclists and multisport athletes to experience power training and provides a path for them to grow into higher level analysis. Riders can upgrade to a Dual Leg Power Meter system by purchasing Pioneer’s right side kit that adds a right side power meter to their existing drive side crank.”

The Single Leg Power Meter and upgrade kit will be available at the end of September. For more information, visit

Pioneering will also be allowing cyclists to send in their existing Shimano Dura-Ace, Ultegra or 105 11-speed crank arm and have their hi-def power meter sensor professionally installed for just $499.
