Stages Carbon GXP for SRAM MTB Power Meter
The Stages Carbon GXP for SRAM MTB Power Meter is a Stages carbon crank arm, made to work on SRAM 1x and 2x GXP mountain cranks. Like all Stages power meters, this unit features +/- 1.5% accuracy and 200 hours of battery life. It is also lightweight at only 15 grams of added weight. The power meter works with both ANT+ and Bluetooth SMART devices, which means you can use it with your favorite bike computer or smartphone. Installation is also easy as you just need to swap the power meter out for your current left side crank arm.
The new Stages Generation 3 power meter features radio antennas that are 6x more powerful than the previous version. This means better compatibility with both bike computers and watches. The new versions also feature improved accuracy and have an LED indicator light for improved ease of use.

Key Product Details
Compatibility:
This Stages power meter is made to work SRAM 1x and 2x GXP MTB cranksets. Please see Compatibility tab for more information.
Power Measurement:
This Stages power meter measures left leg power and doubles the value to account for both legs (assumes both legs are generating the same force).
Key Features:
Affordable, accurate to within +/- 1.5%, lightweight at only 15 grams of added weight, 200+ hours of battery life, CR2032 user-replaceable battery, ANT+ and Bluetooth compatible, easy to install. See Specs tab for more information.
Advice From Our Staff:
Stages left side crank arms are some of our best-selling units. They are affordable and easy to install. The one consideration is they only measure left leg power compared to some other power meters that measure power from both legs (those versions usually cost more however).
Options For This Power Meter
Crank arm lengths: This power meter is available in the following crank arm lengths:
- 170 mm | 175 mm
Compatibility
Crankset: This Stages power meter is made to work SRAM 1x and 2x GXP mountain cranks with a 168 mm Q factor.
Check Frame Clearance: Crank-arm based power meters like this one attach a sensor on the inside of the left crank arm. On some bikes, there is not enough room between the left crank arm and the chainstay for the sensor to clear the frame. Therefore, you should make sure you have at least 10 mm of clearance between the left crank arm and the chainstay - and that you don't have a bottom bracket mounted rear brake (used on some aero and TT bikes). The important area to measure is right in the middle of the crank arm. Please refer to the image below.
If you find that you have around 7-9 mm of clearance, what many people will do is simply install a 1 or 2 mm bottom bracket spacer (between the left crank arm and the frame), which will give them the clearance they need.

Common Questions and Answers
Question: How do I determine what length my current cranks are so I can make sure I get the same size?
- Your crank arm length should be printed or stamped on the inside of the left crank arm, usually near the pedal end.

Great guys and support. Can actually get someone on the line. Easy ordering, fast shipping.
Both bikes run GXP xx1 170mm cranks so went Stages GXP MTB 170mm. So far so good.
xx1 170mm – 182g, Stages 170mm – 217g

This is a very good powermeter. I bought it a couple of months ago and have been using it for about a month. At first it was a bit tricky to make it work properly, cause I did not read the instruction and forgot to make an initial calibration before the first ride, so the data it showed at first was a bit erratic. But after I finally calibrated it (which is very easy using the application that comes with it) everything turned out to work propely. The advice I would give to the new users of Stages Powermeter, – if you, guys, want to make the figures less erratic just use the power indication duration for at least 3 sec. (I use for 10 sec.) to mitigate the spikes that sometimes may occur when you use it. This will make the figures more accurate and readable during the ride. Anyway, this is a very accurate device, I can assure you I have compared it with my first powermeter that I am using recently (it is a powerpod powermeter), Stages crank arm powermeter is a direct force powermeter, hence it gives much more accurate data directly from your crank. So I’m quite satisfied with this excellent product and the servise I got from PowermeterCity shop including direct sale and quick delivery to Russia, which took about 3 weeks.

Great power meter. Works perfect with my SRAM MTB cranks. App setup, calibration and connection was super simple. Accuracy and reliability is why I chose Stages.

had this about six months or so, reads solid, fits perfectly, battery life was a lot better than i expected. What more could you want? Only dinging it a star as the end of the arm is a bit longer and thicker than the XX1, doesn’t change functionality, or even looks really, but would have expected a closer-to-perfect match.

So far so good with this power. Data reads very well. I wish it came with a crank arm boot though – I had to fashion one out of a SRAM one. Note that the total crank arm length is longer than usual; the pedal hole is the right spot but arm extends a little father down under it, making it hard to find a crank boot that fits. Why wouldn’t Stages include one? Every carbon crank I’ve had has come with them. Otherwise, a great product.

Hi Cody. Thanks for the review and I’m glad you are enjoying your power meter. We have requested that Stages add boots to these power meters. In the meantime, please let us know if there is anything else we can do!

This is already my second MTB power meter from Stages. First one was Sram X9 and lasted for 5 years from 2013 to 2018. Will see how long the second one would survive. Excellent service from PowermeterCity shop including direct sale and quick delivery to Russia!

Hi Ivan. Thanks for the review. We trust your new Stages will last just as long as your previous one! We are here if there is anything else we can do.
