Stages Cycling Shimano XTR M9000 Race Single Leg Power Meter Crank Arm

As power meters become ubiquitous with successful road racers, XC racers are readily adapting their training regimens and race efforts with this effective tool. When you're ready to leverage power data for improved training and quicker race times, pick up the Stages Cycling Shimano XTR M9000 Race Single Leg Power Meter Crank Arm. Offered at a lower price than much of the competition, this single leg, power meter crank arm is a great way to enter the world of power meters all while saving some loot for race fees and future upgrades. Equipped with a low profile housing that neatly conceals the ANT and Bluetooth Smart power sensor, the XTR M9000 Race power meter left crank arm adds a scant 20 grams over a standard Shimano XTR M9000 Race Crank. Hollowtech II construction provides an optimal balance of stiffness, strength, and weight savings for dedicated XC racers. The narrow 158 millimeter Q factor is beneficial for those seeking an increase in pedaling efficiency. Please note, this narrow Q factor isn't compatible with some full suspension designs, due to chainstay clearance. The power meter itself boasts an accuracy of 2%, which meets industry standards to satisfy all but the most discerning of data geeks. Active Temperature compensation prevents skewed readings from rapid temperature swings. For simplicity, the accelerometer based cadence measurement doesn't require any additional sensors. Bluetooth Smart and ANT capabilities sync with your favorite cycling apps, wirelessly uploading ride data without dealing with pesky cables. For greater control of the meter, there's an app developed by Stages Cycling. This useful app identifies new firmware to perform wireless updates, zero resets the meter, provides quick read outs of power output, and checks remaining battery life.
