The 4iiii power meter is a left-only crank arm-based power meter and replaces your current left side crank arm. The power meter takes the power that is generated by your left leg and doubles it in order to determine your total power output. The 4iiii PRECISION is one of the most affordable direct force power meters available.The PRECISION is accurate to within +/- 1%. This compares to average accuracy of +/- 1.5-2% for most other power meters. Just swap it out for your current left-side crank arm and you're ready to ride! In addition to ANT+, the PRECISION also transmits data via the Bluetooth SMART wireless protocol. The 4iiii power meter is compatible with XTR M9000/9020/9030 cranksets.
It is also compatible with all other Shimano x000/x020/x030 series MTB cranksets such as the XT M8000/M8020/M8030 or the SLX M7000/7020/7030. It is not compatible with the newer x100 series crankset such as the XTR M9100's, XT M8100's or SLX M7100's.Left or Both Legs Measured. Expert advice and customer service in case you need any help.
