FAQ

Will my Stages Power meter come with a head unit?
No, the Stages Power meter will work with any ANT+™ or Bluetooth 4.0 enabled device, including the iPhone 4s. Riders will need to have or purchase a compatible head unit to complete their power-measuring package.
What head units does my Stages Power meter work with?
The Stages Power meter will work with any ANT+™ enabled display unit, as well as Bluetooth 4.0 enabled devices, including Apple’s iPhone 4S.
I've installed my Stages Power meter and it won't register a cadence or power in the work stand?
Your Stages Power meter will not display a cadence or wattage unless a force is applied to the pedal. If you pedal your bicycle in the work stand it will not register a reading — this is not a problem — as soon as you ride the bike you will see your cadence and power values.
How do I find out if my crank is compatible with a Stages Power meter?

We have options that will fit multiple generations of Shimano Hollowtech II cranks. While we only match the exact aesthetic of the specific models listed on our site, our left power enabled arms fit many more cranks. Furthermore you can mix and match the models in order to find the product with the best price for your budget; example: you can use a 105 level power meter arm with a previous generation Dura-Ace Hollowtech II crank.

For SRAM, we offer Rival GXP and X9 crank arms with both GXP and BB30 compatibility. The Rival crank arm will retrofit to Rival, Force and Red GXP crank arms, as well as a number of SRAM and Truvativ’s non-series GXP models. On the mountain side the X9 based Stages Power meter will fit X9, X0, and the (166mm) XX crank models.

Our Cannondale BB30 based models fit to Cannondale’s proprietary BB30 spindle and serves for both road and mountain bike use.

How do I identify my crank model?

Shimano cranks are all identified with model information above or surrounding the area on the backside of the pedal threads.

SRAM cranks are branded with their model name.

Is there cross-compatibility between base crank models from the same manufacturer?

While we may not be able to match your older model crank with an exact model we will support all Shimano Hollowtech II crank interfaces for road and mountain bikes.

Cannondale’s Hollowgram cranks all rely on the same bottom bracket attachment, which will only work with a Cannondale Hollowgram right crank arm.

How can I find out if my bicycle is compatible with a Stages Power meter?
The Stages Power meter mounts to the backside of the left crank arm we must have enough clearance between the backside of the crank and the frame to mount the meter. Our first baseline test is to measure 8.5cm from the center of the spindle attachment, with this reference point turn your crank so that it’s parallel and in front of your non-drive chainstay. In this orientation place a 10mm Allen key behind your crank at the 8.5cm mark. If the Allen key fits, then our Stages Power meter will fit your frame. If the Allen key does NOT fit, please contact us for further instructions, as a Stages Power meter may still fit your bike.
How do I pair my Stages Power meter to my Garmin or ANT+™ device?
The Stages Power meter is paired like any ANT+ device. In the settings mode on a Garmin you select which bike you are using the power meter on and then scroll down to the ANT+ Power and can either Scan for the power meter or select Sensor Details and enter the ANT+ number that can be found on the back side of the crank arm.
Can I replace the battery on the Stages Power meter without
sending it in?
Yes, the battery is simple and quick to change. You don’t even need any tools. You need a new CR2032 battery and simply turn the battery cover counter clockwise with the tab that sticks out from the battery cover until it stops. Then the cover will come right off. Simply pull out the old battery and insert the new one making sure that you have it in the correct orientation. When installing the battery cover, ensure that the O-ring is still in the intended location to ensure that it has a watertight seal.
Can I retrofit a Stages Power meter to my old crank?
No, the Stages Power meter comes factory installed to a new left crank arm. It is not retrofitable, nor can it be user installed. We factory install Stages Power meters to each of the base crank arms we purchase from Cannondale, Shimano, and SRAM. Installation relies on industrial processes,adhesives, precision, and factory calibration.
How long will the battery last?
The battery will last about 200 hours of riding.
Do I need to calibrate the Stages Power meter?
No, there is no need to calibrate the Stages Power meter. However for best results it is recommended to perform a zero reset before each ride.
Since you are measuring the left side only, do you display just one legs output?
From our testing we have found that there is not a large variation from a riders left to right leg while riding. We make the assumption that your right and left leg’s are doing the same amount of work and double the left leg’s power. So the number that you see while training is for both legs.
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.
Is the Stages Power meter waterproof?
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.
Can I use my Shimano Dura Ace crank (road) on my mountain bike that has XTR?
No, even though the mounting is the same, the width/offset is different between the two.
Will the composite housing fall off of the crank arm over time?
No, it is permanently bonded with a custom designed bonding agent that can withstand over 4,000 psi.
Has the crank arm been weakened by applying the power meter?
No, the application of the power meter will not change the original strength or or life of the crank arm.
Can I install a Stages Power meter to a crank arm myself?
No, the Stages Power meter comes factory installed to a new left crank arm. It is not retrofitable, nor can it be user installed. We factory install Stages Power meter to each of the base crank arms we purchase from Cannondale, Shimano, and SRAM. Installation relies on industrial processes,adhesives, precision, and factory calibration.
