Hit the dirt with power data.
Power meters are as commonplace on road bikes these days as heart rate monitors were around a decade ago. It makes sense since training has evolved and riding with power is more specific and applicable to riding and it better gauges your efforts during races and training. But roadies shouldn't be the only ones with access to this knowledge and the mountain bike set can certainly benefit from this power-derived data too. So for mountain bikers looking to quantify their efforts to support their cross-country racing and enduro stage hunting, the Stages Cycling Shimano XT M8000 L Gen 3 Power Meter Crank Arm lets you maximize your training time on the trails with the ability to stand up to the roughest terrain. Its low barrier to entry is the icing on the cake and takes your perfectly good XT crankset and transforms it into a tool to get you fit quickly.
Inside the IPX7 rated pod are updated ANT+ and Bluetooth LE radios that send information to the head unit of your choice. The sensor is very low profile and withstands creek crossings and post-ride washes. Impressively, the powermeter only adds 15 grams to the original crankarm which is quite negligible considering the amount of data on tap. Just like the standard Shimano XT offering, it can handle regular trail bashings and the crank arm's cold-forged aluminum construction gives us some peace of mind that the crank will survive when we smack it into a rock or root relative to other carbon offerings.
Strain gauges and an updated accelerometer calculate the wattage to within +/- 1.5% accuracy placing it right in line with industry standards, ensuring precise training. Stages utilizes Active Temperature Compensation to accommodate the strain gauges to changing weather conditions before it affects the accuracy of the powermeter. The sensor has an LED indicator that displays battery levels and if you do need to swap it, it’s a simple process achieved by a readily available CR2032 battery. Letting you get the most out of the power meter post ride while also keeping it up to date, the Stages Cycling app identifies and updates the firmware and allows you to zero reset the meter, all wirelessly.
