Stages Cycling performance on Shimano’s best-selling R8000 crank arm
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.
Key Product Details
Compatibility:
This power meter is compatible with Shimano R8000 cranksets. It can also be installed on other Shimano road cranksets, as long as they use Shimano’s Hollowtech II interface. 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 work with most Shimano cranksets, 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:
- 172.5 mm
Other Versions to Consider
Dual-Sided R8000 Crankset: We also sell the Stages Shimano Ultegra R8000 Dual-Sided Crankset which is a complete crankset. It is more expensive, however it measures power from both legs.
Right-Side R8000 Crank Arm: If you currently have a Stages Shimano R8000 left side crank arm, we have the Stages Shimano Ultegra R8000 Right Side Power Meter which allows you to upgrade to a dual-sided power meter. Or, some bike frames cannot fit a left side crank arm-based power meter due to clearance issues with the chainstay. In these situations, the Stages right side power meter is a perfect solution.
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.
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.

Great product and great service!!! The experience was top notch. Note to those with 2019 Trek Domane SL series with disk brakes, the chain stay is close to the crank and the Stages clearence checking tool showed that there may be an interference. After installing the Stages Ultegra powermeter crank on my bike, I found that there is plenty clearance.

Fast shipping, great price and easy to install. Connects with no problem to my phone and my garmin 520 plus.
Been riding for awhile now and got into road biking 3 yrs ago. Got this power meter maybe a yr ago and its been great. I like seeing the data and have definitely gotten stronger.
Power Meter City –
Looking good, Christy! Thank you for the review and the photo! Looks like you are enjoying them! Let us know if there is anything else we can do! Ride safe!
Sam –
Works well, I have 2 stages power meters on different bikes. The power readings from the two different bikes seem to be close to each other, within 20 watts or so.
Power Meter City –
Good to hear, Sam! Good luck on your rides and if there is anything else we can do, please let us know!
Jeff (verified owner) –
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.
Power Meter City –
Awesome! Thank you for this review, Jeff. We are glad you are enjoying your new Stages Shimano Ultegra R8000 Power Meter. If there is anything else we can do to help, please let us know! Ride safe!
Devin Young (verified owner) –
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.
Power Meter City –
Hi Devin. We really appreciate this! Thank you for being a great customer too. We hope you will enjoy your new Stages power mete – good luck on your rides and please let us know if there is anything else we can do! Ride safe!
Tracy (verified owner) –
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.

Hi Tracy, we also want to thank you for being a great customer. We hope you will enjoy your new Stages power meter. We are here if there is anything else we can do!

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!!!

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!

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.

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!

Had some issues with my new R8000 but customer support at Stages was fantastic. After a phone call and an email exchange, Stages decided to send me a new R8000 and have me return the problematic one (don’t ask me what the problem was but it was identified in data I had sent to them). Within two days, I had my new unit and the instructions to return the bad one. Happy counting my watts now thanks to a great company who truly stand behind their products. Now I have to figure out what to make of all this new information!
Power Meter City –
Hi Mark. We are glad you had your problem solved – we hope your new Stages R8000 are working fine now. We want to thank you too for being a great customer. We are here if there is anything else we can help you with!
Alhambro J. Gordon (verified owner) –
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 839 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). It has changed my entire training plan. My legs are no longer spent after my rides because I focus on being in the right power zone during my workout. I’ve been telling all my friends about my new power meter and encouraging them to get one as well.

Hi Alhambro. Good job! We are glad you are enjoying your Stages R8000! We hope you continue to enjoy them and please let us know if there is anything else we can do!

This was my first purchase with PMC. Fast service, no problems at all. The Stages Power Meter was easy to install (I am not a pro and it took me 15-20 minutes to install; plenty videos on YouTube) and worked right away. Little software update, pair with head unit, calibrate, done. I am using the power meter to guide my training. I am very happy with it! Would recommend and buy again.

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!
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.

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 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!

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.

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.

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.

I’ve been using a Stages Gen 3 power meter on a Shimano R8000 left-side crank arm for about a year. So far it’s been almost flawless. I’ve used the power meter extensively both indoors on Zwift and outside. Initial battery lasted more than 2,000 miles. During that time, the meter had a few brief power drops to zero outside or when connected to Zwift. That was annoying but it rarely happens. I’ve ridden in the rain and washed the bike several times with no problems. As for accuracy, it’s within 5-8 watts of my Favero Assioma power meter pedals I used to have. Those Assiomas worked well too but the release tension was so high I injured my knees. So the Stages works better for me because I can use any pedal system I want. Be careful when replacing the battery to ensure the rubber o-ring seal is installed correctly and no contaminants gets inside. And don’t install the battery backwards like I did, it’s a pain to get back out. It’s a solid and reliable power meter.

This is my third power meter from PMC and as usual great customer service and lovely communications. In regards to the stages PM, this is my second 3rd Gen and so far no issues with both and they work as expected with logical and comparable power readings. I strongly recommend PMC and stages PM for every one interested in keeping track of their training objectives.

Hi Waleed. Thanks for the review and for being a great customer! We’re glad the Stages R8000 Gen. 3 is performing nicely for you. Keep up the good work on the bike!
