4iiii PRECISION 3.0 Dura-Ace R9100 Left Arm Power Meter

The perfect complement to a Dura-Ace R9100 setup, this 4iiii PRECISION 3.0 Left Arm Power Meter provides incredibly accurate readings, is only 9 grams and has a long 800-hour battery life. The unit comes pre-installed on a genuine Shimano crank and has a low profile design ensuring it works with the majority of bike frames. 

Patented 3D Strain Gauge technology ensures all power readings take into account changes in pedal stroke, and, when used with the 4iiii app, it's also possible to use the scale factor to account for any imbalances between the left and right leg. ANT+ and Bluetooth connectivity allow you to use the PRECISION 3.0 with any compatible head unit or app, for training indoors and out. 

Even when the conditions are changeable, outputs remain consistent thanks to Active Temperature Compensation and IPX7 waterproofing. There's a light incorporated into the unit, indicating low battery, power and a successfully performed zero-offset, so you'll know when the system is ready to go and when it's time to swap out the battery. 

Please note: Because 4iiii PRECISION 3 power meters are mounted on the inside of your crank, there needs to be enough space between your crank and the frame for the pod to fit. See 4iiii clearance guidelines below to check your frame
