Gen 3 Shimano Ultegra R8000 Dual-Sided Power Meter Crankset

You bit the bullet and upgraded your drivetrain with the new Ultegra 8000 last year, and you're loving the smooth shifting and lightweight feel, but looking for new ways to push your training a little bit further. You've debated delving into dual-sided power meters before, admittedly grazing over them when you saw the astronomical prices — and we don't blame you, but now with the help of the Stages Cycling Shimano Ultegra R8000 Dual-Sided Power Meter Crankset you can push yourself further, making every training hour count, while maintaining the sleek aesthetic of your Ultegra groupset on point. With data collected from both sides you'll find it easier to blast past your old PR's, learning your weaknesses from left to right, independently, so you can push through them to become a stronger cyclist than before.

The key behind this crankset is the little power meter pod affixed to the inner face of the non-drive side, and near the spindle of the drive side crank, which takes what originally was a standard Ultegra 8000 crankset to the next level, and adds the ability to gather pinpoint power data to better measure your ride. It utilizes a blend of strain gauges and an accelerometer to gather position and force data 64 times per second and deliver power readings with a claimed +/- 1.5% accuracy that's right in line with what we'd expect from any quality power meter. Since this model comes with both a drive side, and non-drive side power meter you'll find that the data collected is improved, helping you pin point your strengths and weaknesses left-to-right, to train accordingly and push your power further.

For the gram counters out there, the Stages meter adds a miniscule 20 grams to each crank arm, which is a tiny concession to gain the massive data tracking and training specificity having a power meter affords. To put it in perspective, choosing the smaller safety pins the next time you don a race number should easily balance things out. This bilateral-measuring crankset runs off of a coincel battery, offering up to 200-hours of battery life. Since the meter sits externally on the cranks it's easy to swap mid-season without tools. The meter its self is well encased, earning an IPX7 waterproof rating to give you peace of mind if a storm breaks out on race day. When stormy weather rolls in, or the changing seasons cause the temperature to fluctuate, you'll be happy to find that the power meter has active temperature compensation to continually calibrate to the dropping and rising mercury on your ride, continuing to provide you with accurate data.

What do you think about this product?



I’m trying to upgrade my girlfriend’s 2020 Allez with a full Ultegra groupset. Will this crank and power meter fit in that frame? Would it require the purchase of a new bottom bracket?

Hi Tyler, the Allez has a Praxis Alba crankset which has a 30mm spindle diameter. Shimano cranksets have a 24mm spindle diameter. So, you would need a new shimano bottom bracket. In order to know if the power meter will fit your frame, the non-driveside crank arm needs 10mm of clearance starting at 5cm to 12cm from the bottom bracket center. Otherwise the module won't clear the chainstay.


Your site says you have the stages r8000 LR 172.5 52/36 in stock. stages claims they are back ordered. D o you in fact have them in stock?

Love it!

I've put it through the wringer

Great power meter, easy to install, easy to update, and the data looks accurate. I'm happy to measure each leg's power.

I've put it through the wringer

It's been a couple of months, and I'm still very happy with my crankset! It's been on a couple of rides in nasty weather with no issues, and I haven't experienced any reading anomalies. Five stars from me! Be sure to shoot me an email if you want to discuss in detail!

Yo! I just ordered this product with 165mm crank and a 53/39 chainring for my 2020 Giant Revolt advanced 0 11-speed ultegra 13-34. I have a Garmin edge 520 . Is it pretty easy to install myself or do you recommend I pay my bike mechanic? I don't have torq tools and I'm kinda a n00b with regards to bike mechanics

Happy so far

I've used it once or twice and have initial impressions

Stages Gen 3 units represent a significant improvement over their previous powermeters. The initial set up is very straightforward, and if all goes well, my unit will be as reliable as my single-leg Cannondale crank arm! Updates to come...

How is your experience with stages dual sided powermeter now?

I've had a lot of issues already

I've used it several times

The left side completely died after about a week of riding. But even before that I wasn't getting consistent readings from it. Firmware was fully up to date but it is still clearly an unfinished product. I'm really bummed. Ive owned a few quarqs and power2max and recommend those over this. I really feel like stages rushed this out and didn't get the bugs out yet.
