4iiii has combined their patent pending 3-D tri-axial strain gauge technology, measured at +/- 1.0% accuracy, with Shimano's 12-speed Ultegra R8100 groupset. The result is one of the lightest, most affordable and most accurate direct force power meters available. The PRECISION determines your total power based on the force that is generated by your left leg. This left-only design allows for a power meter that is lightweight and easy to install.
Specifically, the power meter adds only 9 grams to your crank arm and is installed in about 10 minutes. In addition, the PRECISION is compatible with both ANT+ and Bluetooth SMART devices. This power meter is compatible with Shimano R8100 cranksets.It can also be installed on other Shimano road cranksets, as long as they use Shimano's Hollowtech II interface. See Compatibility tab for more information. This 4iiii power meter measures left leg power and doubles the value to account for both legs (assumes both legs are generating the same force).

Please note, the power meter can also be installed other Shimano road cranksets, as long as they use Shimano's Hollowtech II interface. These cranksets can easily be identified by the two opposing pinch bolts that are used to secure the left side crank arm.
