Train smarter.

Maintaining a healthy balance between work, life, and cycling often leaves us more than a little crimped on training time, and haphazardly guiding those precious hours by finicky heart rate data just isn't cutting it anymore. It's time to step up the quality of your training time and swap out your standard Ultegra 6800 left crank arm for a Stages Cycling Shimano Ultegra 6800 Single Leg Power Meter Crank Arm. With a price point that pales in comparison to dual-leg systems, this meter measures power transfer through the left crank to deliver accurate, reliable power data while leaving some cash in the bank for recovery nutrition and mid-ride snacks.


The key behind this crank arm is the little power meter pod affixed to its inner face, which takes what originally was a standard Ultegra 6800 crank arm to the next level and adds the ability to gather pinpoint power data to better measure your ride. It utilizes a blend of strain gauges and an accelerometer to gather position and force data 64 times per second and deliver power readings with a claimed +/- 2% accuracy that's right in line with what we'd expect from any quality power meter.


For the gram counters out there, the Stages meter adds a miniscule 20 grams to the crank arm, which is a tiny concession to gain the massive data tracking and training specificity having a power meter affords. To put it in perspective, choosing the smaller safety pins the next time you don a race number should easily balance things out.
