Power metrics for savvy XC racers.

Power meters are quickly becoming ubiquitous with successful road racers seeking to quantify training and race-day efforts into a wealth of useful data. However, this success is no longer confined to the road, with many XC racers seeking the same data. Upgrade your XC whip with the Stages Cycling XTR 9020 Trail Single Leg Power Meter Crank Arm when you're ready to leverage insightful power data to improve your training and race-day efforts. Offered at an attractive price that leaves spare cash for race fees and future upgrades, this single-leg, power meter crank arm is an excellent choice for improving your physical performance and identifying weak spots across different courses and terrain types.

The low-profile sensor housing neatly conceals the ANT+ and Bluetooth Smart power sensor, preventing it from bashing on rocks or adding much in the way of weight. It's only 20 grams heavier than a regular Shimano XTR M9020 Trail Crank, so you'll barely even notice it on the trail. Cold-forged aluminum construction is more durable than its XTR M9000 Race counterpart, meaning you'll have extra peace of mind across rugged trails.

Looking at the power meter itself, +/- 2% accuracy sits right in line with industry standards, meaning it'll please all but the most discerning of racers and riders. Active Temperature compensation prevents skewed readings when conditions rapidly change on the trail. For simplicity, the accelerometer-based cadence measurement doesn't require additional sensors. Bluetooth Smart and ANT+ capabilities sync with your favorite cycling apps, wirelessly uploading ride data without dealing with pesky cables. Also, there's an app developed by Stages Cycling, which identifies and updates firmware, zero resets the meter, provides quick read-outs of power output, and checks battery levels.

Nice on the wallet

  • Familiarity: I've used it several times

The most cost-effective solution to running a power meter on your mountain bike. It’s single leg, so you don’t get the specific Left/Right data, but for power-based training and understanding what’s happening during your race run, it works perfectly. Must have for the dataset heads.
