Description
The 4iiii PRECISION 2.0 XTR M9000 Left Arm Power Meter is the ultimate setup for the discerning rider looking to monitor and improve their off-road performance. Fitting and maintenance are made simple by the left-hand crank arm design, allowing you to simply bolt this on as a direct replacement.
Adding a mere 9 grams over the standard setup, this sleek design is ideal for the weight weenies chasing incremental gains. Utilising a 100-hour battery life, and with the paired 4iiii app displaying the remaining charge, you needn't ever worry about being caught out mid-ride again.
The 4iiii Patent Pending 3D power meter technology measures Tri-axial strain through the left crank arm. The result is extremely high levels of accuracy, with only a +/- 1% margin of error. As well as power, the Precision 2.0 measures cadence, removing the need for a secondary sensor.
The Precision 2.0 Power Meter is compatible with fitness apps including Strava and Wahoo Fitness, and Garmin, Wahoo and Cateye head units plus others supporting Bluetooth Smart and ANT+.
To check whether the 4iiii power meter will be compatible with your frame, please consult these instructions. Still unsure? Contact us for assistance.
