An affordable entry to power measurement.

Get the edge on the rest of the peloton by swapping out your new redesigned Ultegra 8000 non-drive crankarm with the Pioneer Ultegra Single Leg Power Meter. It utilizes a Lightweight Power Sensor that measures force vectors every 30° of crank rotation, or in other words, 12 points of measurement per pedal stroke, with each point recording a force and a direction. When paired up with Pioneer’s Touchscreen 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.

The Pioneer Power Meter System adds just 64 g to the weight of an Ultegra R8000 crankset for a total claimed weight of 853 g. Estimated operating time is 180 hours on two CR2032 batteries. Available in multiple crank lengths and chainring options.
