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.

    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)

    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.

    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.

    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.

    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!
