Installation was a breeze, very easy. It is working fine and is simple ‘set and forget’, I’ve had no issues so far. The only reason I didn’t give it a 5th star is because the calibration is a bit finicky. It often spits an ‘error’ and I have to try a few times before it completes. I have used it for about 1,500 km now and I am still waiting to see how long the batteries will last.

Hi Jlimo. Thanks for the review. The Stages DA 9100 Crankset has been a very popular product for us so I’m glad you’re enjoying it. We have one on a bike here and it’s been pretty much flawless. Let us know what you find on the battery – it should be good for 175-200 hours. Also, on calibration, just make sure you have that left-side crank arm pointed directly down before you click “calibrate”.

The Stages Dual L/R DA 9100 Crankset is great! Really happy with the upgrade from an earlier generation DA Crankset that did not have power. Instructions are a quick read and will save time calibrating the power meter if you are unfamiliar with the process like I was. After calibration the Stages DA 9100 Crankset Power Meter was dead on when compared to my smart trainer. So far very pleased with my purchase.

Hi Matt. Thanks for the product review! Yea, this is a tough PM to beat. You get a Shimano DA 9100 crankset (best they make) with L/R power and all the bells and whistles (BLE, lightweight, etc.) We hope you enjoy it!

This is my third Stages power meter from Power Meter City. The first two were Ultegra replacement cranksets (dual-sided power) for older Madones that I just upgraded to 11 speed. This one is the Dura-Ace 9100 dual-sided crankset to replace the almost new 9100 crankset that came with my Trek Emonda. The only decision was whether to buy the factory installed complete crankset or to send my existing Shimano 9100 crankset in for the upgrade by Stages. Fortunately, with Power Meter City pricing, it was a pretty easy decision. I just bought the new, complete crankset and I’ll sell my almost-new 9100. It’ll be about the same price.
You might wonder why I use crank-based power meters instead of pedals, since I have multiple bikes. Well, I had Powertap P1 Pedals for about a year and a half and I did like them. They worked very well and were easy to move from bike to bike. But, once I was hooked on power as a training metric, I decided it was worth the cost for me to just have crank-based power meters, so I could go back to using Speedplay pedals… which I love!
So, Stages power meters all-around… and all from Power Meter City!

Hi Steve. Thanks for the great review on your Stages DA 9100 Crankset. Yes, a big advantage to crank-based power meters is that you can run the pedals of your choice. I’m glad it’s working out for you and thanks for being a great customer!
