The Stages Cycling Saint M820/825 Power Meter is the perfect crank arm for downhillers that want to add power to their ride. The crank arm is a perfect replacement for existing Shimano Saint M820-825 cranks and it features a lightweight, technologically advanced unit which allows you to measure pedalling power.

For those of you who are new to Power Meters then here is an explanation of what measuring power can do for you: power is a true metric that remains relatively unaffected by temperature, wind speed, road surface, road grade, time of day, heart rate or any other outside parameter that might affect a cyclists performance. Since power is the most consistent measure of a cyclists effort, it's the best metric to use when tracking a cyclists training. Furthermore, power is the only measure that shows a true change in fitness or the performance of a cyclist over a period of time.

The Saint M820/825 crank arm uses orientation of strain gages to filter any unwanted measurements of deflection. The left measurement also makes calibration easier as no compensation is required for torque differences. The use of accelerometer based cadence allows the Stage Power meter to know if you're pedalling in less than a second. It also eliminates glued or zip-tied magnets, allowing the unit to be completely self-contained.

Riders looking to add power to their crank need only select the required length, as the Stages Power meter fits all Saint cranksets.
