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.

The following tools are typically required 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

Compatibility

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.

    Very easy to install and pair with the Stages app for calibration. I’ve used it with both Wahoo Fitness phone app and a Wahoo Elemnt Bolt V2 for 340 miles with no issues pairing or signal dropouts. This fits my 2019 Canyon Endurace CF SL 8.0 Disc with about 2.5mm min clearance between the sensor and the frame.

    There are 2 aspects to this review that are important – the power meter itself, and Power Meter City. Honestly, they are both 5 stars,

    The power meter itself is exactly as advertised – easy to attach, easy to sync to a garmin, and easy to use. The only thing that threw me for a loop was the need for a Shimano pre-load cap tool (that I didn’t have). I was easy enough to get at the local bike shop, and once I had it, assembly was a piece of cake. It works flawlessly.

    As for Power Meter City – well – in todays times, they were the ONLY place I could find that actually had the Power Meter I was looking for (right size, etc…), including the manufacturer.. Once I ordered it, I got a tracking number almost immediately and had it in 2 days. I was impressed by the inventory, and the purchase to delivery process was flawless. If you’re looking for a power meter, I feel like you can’t go wrong here.

    Unbelievable quick delivery. Will definitely do business again with Power Meter City. Accuracy is close to my wahoo core trainer. The only thing I would have done differently is to purchase both right and left side power meter together. Will purchase the right side once it is in stock.

    This is my second PM, the first one being the 1st gen CycleOps wireless hub which I still have since circa 2008. But I have to say which impressed me the most is the lightning fast shipping! I ordered late Friday, got an email a few hours later that it had shipped. Being the weekend, I thought I’ll get it, maybe middle of the following week, but no, I got the PM that Monday! Keep up the good work, its small stuff like this that keeps customers happy and coming back!!!

    • Power Meter City

      Hi Rannie. Thanks for this kind review on your Stages Shimano Ultegra R8000 Power Meter. Congrats on your 2nd PM BTW! We hope you continue to enjoy them and please let us know if there is anything else we can do!

    New to cycling the last 4 mos. My first power meter is the ULTEGRA R8000. Ordered one of the last units in stock on Saturday. Arrived at my home on the east coast on Monday (2 DAYS!). Customer service was awesome helping me figure out what I needed and helped make sure the crank arm would clear my 2020 Trek Emonda chainstay (no problem!). Great product, great service. Thanks PMC!

    • Power Meter City

      Hi Todd. Thanks for this! We are glad it arrived on time as expected. Good choice for your first power meter! We are here if there is anything else we can do!

  8. Andrew (verified owner)

    Only a few rides on which to base my opinion, but very happy with the performance. I do not have a way to check accuracy, but the data appears consistent and no drop outs have occurred so far. Overall I am pleased with the purchase.

      Hi Andrew. Thank you for leaving us a great review on your Stages R8000 Power Meter! We hope you continue to enjoy them. Good luck on your future rides and please let us know if there is anything else we can help you with!

  9. Joel (verified owner)

    I am very happy with the Stages power meter. I was using a PowerTap hub for 7 years or so. The Stages allowed a super-easy transition with my Wahoo Bolt GPS unit. I highly recommend the Stages product. I carefully measured the clearance between the Crank arm and the bike frame to make sure there was room. It appears the Stages restrictions are conservative as there is plenty of room. A truly excellent product.

    • Power Meter City

      Hi Joel. Good job and good choice! To be sure we always tell our customers to check the frame clearance and we are glad it has room on yours! We hope you continue to enjoy your new Stages. We are here if there is anything else we can help you with!

    Excellent product, been using it about about two weeks now and it’s doing what it should, so happy. Customer service was excellent, and I’ll be buying again from Power Meter City when the time comes. Two thumbs up for sure.
