Stages Power Meter Description:

The Stages Power Meter takes a Shimano non-drive-side 105 7100 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 ton 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 can 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 an easy-to-replace battery, the power meter is fully waterproof, so you don’t have to worry about sending it through wet and muddy conditions.

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.
