Arron O.wrote a review of Stages Cycling Shimano Dura-Ace R9100 Gen 3 Dual-Sided Power Meter Crankset on October 31, 2018
Familiarity: I've used it several times
After putting roughly 500 miles on this gen3 Stages, I can tell you its much improved over the gen2. No dropout of signal, I get a constant reading of my power. Quite honestly, that's all we're looking for, right? Consistency and reliability. I've had Quarq, they're great. I've used the new Shimano 9100P, very, very good. Even though the Shimano 9100P tends to measure output slightly lower than that of the Quarq and Stages Gen3 - with the same effort - at least it's consistent. The Stages Gen 3 seems to be at least equal to the Quarq, which is exactly what I was looking for. Nice job by Stages to fix the bugs with the Gen3 model so it hooks up consistently, and reads consistently with the Garmin computers. Just to be clear, the issue with the Gen2 model was with the Garmin from what I noticed. Make sure you calibrate the power meter with your computer!!
