Shimano XTR M9020 Trail L Gen 3 Power Meter Crank Arm

More and more successful racers are using power meters that it's almost become ubiquitous on the road as its ability to quantify both training and race-day efforts provide a wealth of useful data. Power meters are no longer confined to the road and many XC, enduro, and even DH racers are seeking the same data as the road set. Stages Cycling now gives you the chance to upgrade your cross-country or trail bike with the Shimano XTR M9020 Trail L Gen 3 Power Meter Crank Arm when it's time to value insightful power data on every training ride and race. This unique approach allows you to keep your driveside XTR Trail crankarm and ring(s) and comes in at an attractive price that leaves money for entry fees and travel. The left, single-leg, power meter crank arm is an excellent choice for improving your fitness and charting your abilities across different courses and terrain.

This low-profile pod houses the recently updated ANT+ and Bluetooth Smart antennas, providing a 6-time stronger radio transmission so your head unit doesn't miss a watt. Its small, tucked away design prevents it from bashing on rocks or adding much in the way of weight. It's only 15-grams heavier than the standard Shimano XTR M9020 Trail Crank, so you won't even notice it on the singletrack. The same cold-forged, hollowtech aluminum construction is present on this arm so upgrading to this powermeter is truly plug-and-play.

The power meter itself exhibits an impressive +/- 1.5% accuracy which sits inline or slightly better than industry standards, so your metrics are more meaningful and your training is more precise. Stage's Active Temperature Compensation prevents skewed readings when temperatures change on the ride. For simplicity, the updated accelerometer reads cadence without additional sensors. The Bluetooth Smart and ANT+ capabilities allow you to sync with your favorite cycling apps, wirelessly uploading ride data without plugging in. Also, there's an app developed by Stages Cycling, which identifies and updates the firmware, zero resets the meter, provides quick read-outs of power output and checks battery levels. And if you're worried about water ingress, rest assured as Stages has bestowed an IPX7 rating meaning the meter is fully protected even while being submerged in 1m of water for up to 30 minutes.
