The Stages Power Meter takes a Shimano non-drive-side Dura-Ace 9100 series crank arm and adds a Stages Gen 3 power meter for all the performance and data you can expect from these two best in class brands. If you want to get the most out of your training then getting the best power meter is the ideal tool to quantify your rides. Stages Power Meters allow you to gather precise and accurate data without adding a tonne of weight, making major component changes to your bike or breaking the bank.

The Gen 3 Power Meters use strain gauges and an accelerometer to gather data 64 times per second with an impressive +/- 1.5% range of accuracy, half a percent more accurate than previous models. The Gen 3 Power Meters also feature Active Temperature Compensation - meaning that the power meter continuously recalibrates across temperature fluctuations during your ride. It continues to provide accurate data regardless if the weather goes from full summer sun to freezing hail in a matter of minutes.

Stages is able to fit all this technology into a tiny 20 gram package that uses a coin cell battery with 200 hours of life. On top of being unnoticeably small and with a mindlessly easy to replace battery, the power meter is fully waterproof so don’t have to worry about sending it through wet and muddy conditions.

Stages uses cranksets already on the market, meaning you can add a power meter to your bike without changing its fit or performance. If you’ve dialed in fit metrics like crank length and q- factor, or simply don’t want to change the style of your bike, you don’t have to compromise on these details for data. Available in multiple crank lengths, brands and models, you’re sure to find the right crankset for your bike.

Finally, the Gen 3 Power Meter cranksets allow you to gather data equal or greater to other power meters on the market, but at a fraction of the price. This means you can save that money for more bike parts, or to attend more races, or to partake in more post-ride celebrations for all the goals you achieve. Take the guesswork out of your training and push yourself further with the Stages Power Meter Crank.
