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.
