Stages Shimano GRX RX810 Power Meter
The Stages Shimano GRX RX810 Power Meter brings Stages power to your gravel bike! Compatible with all Shimano GRX cranksets, the Stages power meter is accurate, durable and race ready. The power meter is also extremely lightweight – adding only 15 grams to the weight of the crank arm. All Stages power meters are compatible with both ANT+ and Bluetooth SMART devices, which means you can use your favorite bicycle computer as well as a smartphone or tablet.
The 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 (+/- 1.5%) and have an LED indicator light on the housing for improved ease of use.
~Stages Rider Support~
It has come to our attention that Stages no longer has the resources to offer product support or warranty services.

Key Product Details
Compatibility:
The Stages Shimano GRX RX810 Power Meter is compatible with all 11- and 12-speed Shimano GRX cranksets including GRX 600, 610, 810 and 820. 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:
This is a great way to add power to a Shimano GRX crankset. This Stages power meter is affordable, easy to install and works well. 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 | 172.5 mm | 175 mm
Compatibility
Crankset: The Stages Shimano GRX RX810 Power Meter is compatible with all 11- and 12-speed Shimano GRX cranksets including GRX 600, 610, 810 and 820.
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: Is this power meter available in a GRX 600 version?
- No, this power meter only comes in a GRX 810 version. This is because, the backside of the GRX 600 crank arm is not flat, rather it has ridges, and therefore a sensor can’t be attached to it. However, this GRX 810 power meter also fits on Shimano GRX 600 cranksets.
Question: Will the Stages Shimano GRX RX810 Power Meter work on my GRX RX600 crankset?
- Yes, the Stages Shimano GRX RX810 Power Meter is compatible with both the Shimano GRX RX810 and GRX RX600 cranksets, as they both use the exact same interface. Please see our full article for more information: Will the Stages Shimano GRX RX810 Power Meter work on my GRX RX600 crankset?
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.
Question: Do you also stock new chainrings for my Shimano GRX crankset?
- Yes, we have several Shimano GRX Chainrings to choose from, including 1x or 2x and round or oval.

This has nothing to do with Power Meter City. However, a prior acknowledgment that Stages Customer Support is non-existent would have been nice. So here’s the story.
I’ve been trying to reach Stages support for over a month regarding my crank arm, and they refuse to respond. I’m pretty sure I’ll never hear from them based on what I saw on their Facebook page. Some people have support tickets open for almost a year now with no response.
I recently competed in a Century Ride, and while riding, my arm disconnected from my Wahoo and would not reconnect. I wasn’t all that surprised, as I had forgotten to replace that battery the night before. It rained for almost the entire ride, so things got messy. The following day, while inspecting my bike and prepping it to be cleaned, I went to swap it out for a new battery. I tried everything to get it to reconnect, including the reset method. But nothing is working. Also, to be clear, this was the very first time opening the battery enclosure. After further googling, someone on Reddit mentioned inspecting the O-ring to ensure it wasn’t damaged or getting in the way. The weird part is that I don’t recall ever seeing an O-ring. So I returned to the bike, and to my surprise, there was no o-ring inside. I hadn’t moved the bike, so I searched the area, but there was nothing to find.
So here’s my concern. Without the O-Ring and given all the rain and flooding during the Century Ride, my concern is the crank arm suffered water damage and is now no longer functional. Stages support has ignored my support ticket for over 4 weeks, and I’m so frustrated with this whole process. I’m ready to throw it out.
Up until it stopped working, it was great. But I’ll never buy from this brand again.

This is my second Stages left crankarm power meter. (my other one is Shimano XT on my Pivot mtb). In my experience, Stages power meters work great, and for my purposes, there is not much information lost with a left-side only powermeter when compared to a dual-sided meter, which I have on my road and Tri bikes.
Good battery life, and I never seem to lose the signal in either my Garmin 1030 or Garmin Fenix 6. The Stages unit calibrates and pairs quickly.
As for Power Meter City, very nice inventory, great information regarding compatibilty, and super prompt delivery.

Thanks for review Paul. It’s great to hear your insight and hope this continues to work well for you.

This is my second Stages power meter – both LH cranks. Simple and easy to set up and fit, with an accurate enough (although left biased) output for 95% of people. Minimal fuss and maximal effort.
Batteries (CR2032) last about 3 months and are a simple exchange taking seconds. integrated with my Garmin, you get about an hour or so warning of critical battery life once it goes – plenty.
As for Power Meter City – i have bought direct from Stages and from them. Stock levels good and exactly what i wanted. Seamless and delivered in a few days. Happy rider.
recommended all round.

First off, I want to say just how easy it was to order from powermetercity.com. I placed my order on December 14th and was given an update on the status later that day. Tracking information was provided the next day. It arrived on the 18th. West Coast to East Coast in four days during the Christmas season. Impressive. Really like doing business with Power Meter City!
The Stages meter has exceeded my expectations. It immediately was recognized by my biking computer and has provided accurate and reliable data every ride. I have not lost connection once with it.

I haven’t had a chance to use the power meter yet, as I am still waiting for the bike to arrive. I am certainly pleased with the service from Power Meter City. Not only did they call to doublecheck my address, but it arrived quickly and in great shape. Hopefully the bike will arrive soon, so I can give it a workout!

This is my second Stages left side. I have an Ultegra left side on my road bike. The GRX version works just as well. I get similar power readings from either bike on known segments which is what I was after. Both connect seamlessly with my Wahoos and with Zwift. Power Meter City will keep getting my business.

Rock solid power meter! Accurate, easy to setup, easy to use, no complaints about the hardware. Only ding I can make is with the software. The Stages iOS app is a little clunky but works. Doesn’t take anything away from the quality of the hardware really. Only concern there would be with the battery cover. Not 100% sure just how well it’ll hold up to bike washes. Guess we’ll see! 😛
