Stages Shimano DURA-ACE 9100 Dual-Sided Crankset

The Stages Shimano DURA-ACE 9100 Dual-Sided Crankset is the company’s top of the line power meter. Using Shimano’s leading DURA-ACE 9100 crankset, this Stages power meter features dual left/right power measurement. With a power sensor on both crank arms, the power meter can measure left and right leg power independently and transmits this data in real-time to your bicycle computer. This left/right power measurement is all new to Stages power meters and makes the Stages 9100 Power Meter a valuable training tool!

Like all Stages dual-sided cranksets, this unit is accurate to within 1.0% and features dual ANT+ and Bluetooth SMART compatibility and runs off of easy to replace CR2032 batteries. In addition, the Stages 9100 Dual-Sided Power Meter is extremely lightweight, adding only 35 grams to the crankset.

    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!
