Stages Cycling FAQ

General

How can I find out if my bicycle is compatible with the stages power meter?

Please see our frame compatibility guide here.

Can I send in my old power meter to be updated to the new design?

At this time, we are unable to offer the option to update existing functional first generation power meters to the new housing design. The basic principles of the power meter remain the same, with the same means of measuring power, accuracy level, and reliability, as well as the same firmware, which continues to have ongoing updates for improvements and bug fixes.

Is the Stages Power meter waterproof?

The Stages Power meter is manufactured to the IPX7 water resistance standard. It can withstand the harshest down pours and being fully submerged in a stream crossing. However, it should not be put in a high pressure situations like being directly sprayed with a pressure washer or deep sea diving mountain biking.

What head units does my Stages Power meter work with?

The Stages power meter will work with any ANT+ enabled head unit, as well as many Bluetooth iOS and Android devices.

Can I send in my crank arm to build into a Stages power meter?

No. Stages power meters are sold as ready to ride units only.

What is the warranty on the Stages Power meter?

All Stages Power meters are warranted to be free from any manufacturing defects for 1 year from the purchase and/or in accordance with your State or Province.

Can I use the Stages Power meter with oval or Osymetric chain rings?

Mechanically, the Stages Power meter is 100% compatible for use with Osymetric, Q-Ring, Absoluteblack, and other non-round chain rings.

Our power measurement through a Stages Power meter is event based, where as an event is one complete pedal revolution. Due to the changes in velocity non-round chain rings produce through the course of an ‘event’ you will see that your power will be skewed higher than with a round ring, which has a constant velocity throughout each event. Through our own testing, and using a hub-based meter as a control, we conclude that there will be a 4-5% increase on the readings from a Stages Power meter when used with a non-round chain rings. We recommend that our customers take this into account when changing from round to non-round chain rings, as they may need to adjust their functional threshold power accordingly.

 

Installation

Can I install a Stages power meter myself?

Yes. Installation of a Stages power meter is very simple. You simply remove your current, left-side crank arm and install the Stages in its place. No special technical skills are required. Installation typically takes less than 15 minutes.

 

Battery

How long will the battery last?

The battery will last about approximately 200 hours of running time.

How do I check if my battery is running low?

The Stages power meter calculates an estimated battery life remaining which can be checked using the StagesPower app or certain head units that enable this feature.

  • If you have the StagesPower app installed on your smart phone or tablet, you can easily check the status of your power meter’s battery. The StagesPower app displays an estimated battery life in the lower right corner of the app’s home screen. The battery indicator may take 5-10 seconds to show up after a connection is made through the app, but once it loads will give you an easy visual reminder on how much battery life you should expect. This battery indicator will display green from the time the battery is new until it starts to run low, then changes to yellow when the battery has only 15-20%, and red at 5% or less power remaining. Keep in mind that battery life is being estimated and that expected remaining time can vary slightly.
  • On some Garmin models, you are able to check your battery status within your head unit. The power meter does only send battery updates every few minutes, so it may be helpful to check after the power meter has been on and connected to the Garmin for several minutes, otherwise the Garmin may report that sensor information is unavailable since it has not received the information yet.

Can I replace the battery on the Stages Power meter without sending it in?

Yes, the battery is simple and quick to change and does not require any tools. Before changing your cover, please note whether your Stages Power meter has our original or second generation plastic housing design, as the process to change the battery is slightly different.

First Generation

  1. To remove the battery: Rotate the battery door into the “open” position and gently lift outwards to remove the battery door from the unit. If needed, use your finger to tilt the battery and lift it from the compartment. Avoid using sharp tools to remove the battery, as they can cause damage to the electronics within the power meter
  2. Insert a brand new CR2032 battery into the battery compartment, with the positive (+)  side facing outward
  3. Before replacing the door, inspect the o-ring to ensure it is properly sitting into the channel and not twisted, broken, or partially sticking out
  4. Re-insert the battery door into the power meter housing aligned with the “open” position
  5. Rotate the cover clockwise into the closed position to lock the battery door into place

Second Generation

  1. To remove the battery: Rotate the battery door into the “open” position and gently lift outward on the battery door to lift out the cover and battery
  2. Insert the new CR2032 battery into the battery door, with the positive side facing the battery door
  3. Before replacing the door, inspect the o-ring to ensure it is properly sitting into the channel and not twisted, broken, or partially sticking out. Note: If needed you may want to angle the bike so that it is not at a 90 degree angle where the o-ring can easily fall out
  4. Re-insert the battery door into the power meter housing aligned with the “open” position
  5. Rotate the cover clockwise into the closed position to lock the battery into place

 

Calibration

How do I calibrate my Stages Power Meter?

Using your bicycle computer:

  1. Spin the cranks backwards a few times to wake up the power meter
  2. Align the crank arms vertically with the left arm in the 6 o’clock position and right arm in the 12 o’clock position
  3. On your bicycle computer, navigate to the calibration page and select Calibrate
  4. You should receive a message saying “Calibration Successful”

Using the StagesPower app on your mobile device:

  1. Spin the cranks backwards a few times to wake up the power meter
  2. Align the crank arms vertically with the left arm in the 6 o’clock position and right arm in the 12 o’clock position
  3. Open up the StagesPower app on your mobile device and select “Connect via Bluetooth” on the iOS app or select the power meter from the list of Discoverable devices on the Android App
  4. Select “Zero Reset” from the app. A zero reset value will appear under “ADC” once the process is complete
