Knowledge of created power data allows you to exploit your strengths, improve your weaknesses, and plan crucial recovery. This goes for a rider racing World Cup, or an Enduro rider looking for every performance edge. Energy expended impacts overall fatigue and handling capability and can be accurately assessed with a single leg unit. This keeps the Stages unit affordable, compact, and easy to use. The key for Stages is that theirengineers found through thousands of miles of testing research that power differential between legs has no significant influence on ride data and its value as a training tool. This helps to significantly reduce complexity and cost while providing power measurement with ±2% accuracy. Having Active Temperature Compensation (ATC) is far more important to a mountain biker, as it takes place automatically and continuously while you pedal, allowing you to simply ride and use utilize your data without worrying about manual adjustments.

It is crucial for accurate training and analysis that the meter be consistent to itself, that the rider can quickly and easily set Zero calibration at the start of every ride, and that temperature is continually accounted for. As Stages constantly corrects for temperature, accuracy is much better over many of it's competitors (whose units don't auto correct, or do so with far less frequency) whenever there is a significant change in temperature during your ride. Temperature can seriously affect the strain gage systems used to measure power, to the point where a long climb in the mountains during which weather and temperatures can greatly fluctuate, uncorrected data is nearly worthless.

In this model, Stages bonds the actual power measurement pod onto a new Stages Carbon GXP MTB left side crank arm. The location on the arm is crucial, as the arm and pod then tested and calibrated together to ensure that the strain gages and sensors are working optimally with the specific crank arm. The pod itself is made of an incredibly strong polycarbonate blend that is similar material to that used in bulletproof glass. This material is perfect due to its light weight, superior durability and impact protection, so there is very little chance of an impact breaking the housing without also seriously damaging the crank arm. Additionally, the Stages Power Meter is highly sealed against environmental conditions, and carries an IPX7 water resistance rating, which means it can be submerged in water up to 1 meter for a maximum of 30 minutes.

It was crucial to Stages to make their power meter efficient, as well as keep their firmware updated. This version of the Stages Power Meter is their Gen3 pod, which is more streamlined than the original model (allowing for more crank arm and frame compatibility)and offers improved communication overall, and very specifically with compatible sport watches. The battery compartment and door were improved and strengthened. It is easy to change the battery, a coin-style, readily available CR2032 model. Each CR2032 delivers 200+ hours of power to the unit. The StagesPOWER App also keeps track of the battery level, so you can be prepared. Firmware is updated via this smartphone app as well. Stages regularly advances their firmware and app to reflect new features and updates. The app is user friendly and will become your best friend as you manage your power meter, allowing for direct updates to Training Peaks, Strava, Garmin Training Center and other cloud-based training systems.
