Pioneer has been at the forefront of consumer electronics since the dawn of the digital age, so when cyclists working for the electronics giant all around the globe decided to make a power meter, the outcome was already a foregone conclusion. With the resources and experience available at Pioneer, their Power Meter System would be a solid performer and a solid game-changer.

Often times, the fastest riders in the peloton aren't just the strongest riders, but the smartest and the smoothest. Saving energy wherever possible is paramount when it comes to winning races, and you'll find one of the places where you can save the most energy is your pedal stroke. At the core of the Pioneer Power Meter System are dual strain gauges (one for each crank) that measure force vectors every 30° of crank rotation, or in other words, 12 points of measurement for each leg every pedal stroke, with each point recording a force and a direction. When paired up with Pioneer's Touchscreen Cycle-Computer, this information is analyzed and displayed in real-time to show you not only how much power you're putting out but also, by utilizing the vector data, how efficient you're being with your power. After all, putting out 400 watts for 20 minutes certainly sounds impressive, but it might not amount to much if you're applying all that force in any other direction than what is optimal to spin the crank around.

With the Pioneer Dura-Ace 9000 Power Meter Crankset, invaluable power measurement is combined with Shimano's top-tier crank for the ultimate tool to enhance your race and training performance. The Pioneer Power Meter System adds just 64 g to the weight of a Dura-Ace 9000 crankset for a total claimed weight of 707 g. When used with third-party ANT+ capable cyclo-computers, power numbers are available according to the features of the paired computer. Estimated operating time is 180 hours on two CR2032 batteries. Available in multiple crank lengths and chainring options.
