Daniel J.wrote a review of Stages Cycling Gen 3 Shimano Ultegra R8000 Dual-Sided Power Meter Crankset on April 27, 2018
Familiarity: 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.
