Stages Shimano Ultegra R8000 Dual-Sided Crankset

The Stages Shimano Ultegra R8000 Dual-Sided Crankset features Stages proven performance and dependability on a Shimano Ultegra R8000 crank. This unit is accurate to within 1.0% and like all Stages power meters, features dual ANT+ and Bluetooth SMART compatibility and runs off of easy to replace CR2032 batteries. In addition, the Stages R8000 Dual-Sided Power Meter is extremely lightweight, adding only 35 grams to the crankset.

However the key feature on this power meter is its ability to measure left/right power. With a power sensor on both crank arms, the power meter can measure the force generated by each leg individually and transmit this data in real-time to your bicycle computer. This left/right power measurement is all new to Stages power meters and further makes the Stages R8000 Power Meter a valuable training tool!



Chainrings: 50/34 | 52/36 | 53/39

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



The Stages R8000 Dual-Sided Crankset is compatible with all Shimano Hollowtech II road cranks.

    I was looking to purchase shorter cranks to replace my current Praxis with C1 power meter. The Stages Ultegra Dual side PM came in at about 400grams less than my previous setup and the shorter cranks smoothed out my pedal stroke significantly. Great price and service from PMC.

    Ordered on a Friday and got it on Monday. Impressed with that. Also got the L50 Dash. I am an experienced mechanic so crank install was a breeze. 11 speed crank works flawlessly with my 7800 10-speed drivetrain. Setting up the dash was a bit tedious but only because I have been an old-school analog computer user. Got everything dialed in and so far so good. Using mostly indoors with Inside Ride rollers and the combination of power meter and active rollers has transformed my indoor riding.

    Decided on the L/R Stages Gen 3 power meter due too an old injury on the Left leg. Bottom line, the unit works as advertised. The efforts I have been putting in feel very similar to the power output from my indoor trainer. I have rode 10 hours now on the road with the Stages pwoermeter. As for Power Meter City, they delivered fast and in good shape. Took the Stages Unit to my local bike shop and had it installed. All in all, highly recommend the Stages Gen 3 L/R unit and Power Meter City. thanks for the help

    I have to say that as many questions that I asked Power Meter City you would think they would say stop emailing us and buy something. Not the case here, they were professional and very knowledgeable. The most impressive thing to me was that they did not push the most expensive options on me. Just gave me recommendations on what I needed. Now on to the Stages Ultegra gen 3. Simply put I have zero issues and I trust the numbers. I ride with other riders that have all different types of power meters and they are all close on the numbers. I have no doubt that if I were to have a problem I would receive help as soon as I asked for help. I am a service member stationed overseas in Japan and the shipping was just as good as the other customer service that I was provided. Buy from Power Meter City. Thank you for great service and a great product.

    I’ve waited a few months before reviewing this product to make sure it’s reliable, accurate and durable. I’m happy to report that apart from the occasional 1 to 2 second drop in communication to my Garmin Fenix 5X it’s been all of these.

    I recommend the L/R meter for indoor training. I found that on the road I had a 50/50 balance between left and right, but that indoors I tended to have a 55/45 balance which over time I’ve managed to get close to an even balance thanks to the immediate feedback it gives me.

    In addition to being a great product I really enjoyed the customer service. I train in the Philippines near the sea under high humidity. Because of this I asked for some additional battery seals, which they provided free of charge. Also, although my shipment was delayed due to buying on Black Friday, they kept me up to date on shipment dates, and sent it priority shipment at no extra charge. Now that’s looking after your customers!

    These guys are the best! I’ve placed a couple orders with them now and the product works flawlessly. Accurate. Easy to install and use. The only thing better is their customer service.

      Thanks for the review and for being a great customer. These Stages cranksets are fantastic and we’re glad it’s working out for you!

    This is my second Stages Shimano Ultegra R8000 Dual-Sided Crankset from Power Meter City. I have one more bike remaining that needs a power meter, which will probably be the DuraAce L/R crankset from Stages. I can now return to using my Speedplay pedals after two years of using power meter pedals. And these power meter cranksets work just as well as the pedals did. Easy to install and pair and the connection is solid.

      Hi Steve. Thanks for the review and for being a great customer. I’m glad the Stages Shimano cranksets are working out for you. We are here if we can help you with anything else!

    I bought this for rehabilitation purposes as I felt I was not using my injured left leg after a knee operation. 12 months in and 3000km later it has been perfect. Will probably get the DA one for my other bike as well as it provides all data required. My Garmin gives me immediate & accurate left / right Watts with each pedal stroke and I have consciously gone from 60/40 to a close 50/50 output helping me with my “lazy “ leg. Service was good and delivery to Thailand prompt.

    • Power Meter City

      Hi Jim. Thanks for the review. Sounds like you’re crushing it with your Stages – nice! We’d be happy to help you with the DA 9100 – just let us know!

    Bought the Stages R and paired it (with the app) very quick and easy. Accurate (power against Assioma) no deviations and all the information your heart desires. Great product – Great sale (again)
