Stages Shimano Ultegra R8000 Power Meter

The Stages Shimano Ultegra R8000 Power Meter combines Shimano’s award-winning Ultegra groupset with Stages Cycling’s proven performance and dependability. The result is an accurate, lightweight, durable power that comes ready to ride on a Shimano R8000 crank arm. Compatible with all Shimano Hollowtech II road cranks, the Stages Ultegra R8000 runs off of a CR2032 battery and features 200 hours of battery life.

In addition, the power meter is 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 R8000 power meter (Generation 3) 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.



Proven Performance

Since 2012, Stages has been making some of the most popular power meters. Accurate to within +/- 1.5%, Stages power meters are used by amateurs, pros, and everyone in between

Easy to Use

You can install a Stages power meter and be up and running in minutes. Simply remove your current left-side crank arm and bolt on your Stages power meter. No special technical skills required!

Long Battery Life

On just one CR2032 battery, the Stages provides 200 hours of battery life. In addition, the power meter offers tool free battery replacement. You can have the battery changed in about 60 seconds!

ANT+/Bluetooth SMART

With both ANT+ and Bluetooth SMART capabilities, you can use the Stages power meter with your favorite bicycle computer, smart phone, or tablet.


The Stages power meter adds a mere 15 grams to your bike. This makes it one of the lightest power meters you can buy.


Crank arm lengths: 165 mm | 170 mm | 172.5 mm | 175 mm


Tools Needed for Installation

You will need the following tools for installation of this product. You can purchase many of these commonly used tools in our store.

  • Shimano Crank Arm Cap Tool (sold by us separately)
  • 5 mm Allen key


Crankset: The Stages Shimano Ultegra R8000 Power Meter is compatible with Shimano R8000 cranksets.

Please note, the power meter can also be installed other Shimano road cranksets, as long as they use Shimano's Hollowtech II interface. These cranksets can easily be identified by the two opposing pinch bolts that are used to secure the left side crank arm. Please see the image below and contact us if you have any questions on compatibility.Shimano Hollowtech II Left Crank Arm

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.

  1. Bill (verified owner)

    Josh was extremely helpful working out some frame clearance questions (there’s plenty of space on a Canyon Ultimate (M) with 172.5 mm cranks, event though it fails the AAA test).

    The power meter is very easy to setup and works great!

  2. Iain S (verified owner)

    Thank you PMC. The product arrived in HK without a hitch and installation was simple. Paired with my old Garmin Edge 520 and newer Fenix 6 without any problems.

      HI Iain. We are glad you liked your Stages! Good luck on your future rides and please let us know if there is anything else we can help you with!

  3. Tom Watterson (verified owner)

    This is my first power meter and I bought it so I could use it on two bikes. So far it has been working great and it is easy to switch between the bikes. My computer (wahoo element) immediately recognized it and added a new field on my screen for power and now I also have cadence information without an attachment to my crank arm. Only complaint is I wish I bought this sooner. Thanks

    Great easy process and very quick shipping. 200 miles on it so far and very happy. Highly recommend.

      Hi Mark. We are happy and thankful for your business here with us. Please let us know if there is anything else we can do!

    Great support/advice and quick shipping to Canada. Power City had, by far, the best price on the Stages Ultegra meter, even when considering shipping, duties and Canadian taxes.

    The unit itself was very simple to install and has worked flawlessly. Using a power meter has been an absolute game changer for my training. Thanks!

    • Power Meter City

      Hi Matt. Agreed! We wanna thank you for being a great customer too. We hope you continue to enjoy your Stages and we are here if there is anything else we can do!

    Power meter is easy to install and works very well! Also, very easy to set up! Great service from PMC! Arrived in a couple of days. All around great !

  7. Matthew Barnes (verified owner)

    So glad I bought this. PMC had the best information of any store, and so decided to purchase here. The Stages Ultegra R8000 crank is extremely easy to install (It’s just a crank arm), and getting it paired with my Garmin 520 edge was very easy. Calibration is easy as well. I knew what my FTP should be based on regularly using my Wahoo Kickr with Zwift, so taking the new power meter out on a 75 mile gran fondo this weekend was awesome. No more wondering if I’m pushing too hard; it was my fastest time yet. Well worth the money.

    • Power Meter City

      Hi Matthew. Truly an amazing power meter crank – worth the money! We also want to thank you for being a great customer. Please let us know if there is anything else we can do!

    Next to my helmet, the best riding addition I have made to date.
    Easily justifies the price. Paired with my Yahoo Bolt well.
    Amazing amount of data for each ride.
    The information provided is useful and makes riding so much more fun and helpful to training.

    • Power Meter City

      Hi Steve. Good job on your training! We are glad you are enjoying your Stages Shimano Ultegra R8000. We are here if there is anything else we can do!

  9. MAKOTO HARA (verified owner)

    My first power meter was installed at the end of last March. So far it has been providing valuable information for my motivation and management for my performance. I had been worried to buy whether it could be installed or not, because my Treck Emonda SL5 of 2018’s had very small clearance between the crank and chain stay of size 50. I would like to inform my data for prospective users as follows:
    Crank + sensor : about 22.8mm
    Min. remained clearance between sensor and stay: about 3.1mm
    I hope this information help them!

    I’ve only been using my power meter for a few weeks but so far it’s been great. Having the watts display on my Garmin 520 has really been motivating, seeing where I’m spinning too fast or grinding too hard and wasting effort has already resulted in better average speeds (wind permitting). Having a more accurate estimate of calories burned is also quite motivating, without the power reading the Garmin unit apparently uses heart rate to calculate calories burned. I’m heavy for my size so my heart beats faster than it should making it seem as if I’m burning more than I actually am. I went from having it show around 800 calories an hour to about 600, I’m sure it’s not completely accurate but certainly better than before.

    • Power Meter City

      Hi Steven, Thank you for the amazing review. We are glad you are performing well with your stages. We hope you continue to enjoy it and are here if there is anything else we can do in the future!
