GRX 810 Rear Derailleur 11-40 Compatibility
I would like to use an 11-40 Cassette on my new 2X GRX build and wondering if anyone here is using this configuration. 48-31 Crankset and GRX 810 rear derailleur, does it have enough capacity to go from big-big to small-small without breaking anything in a real-world application. There are one or two videos on YouTube saying yes, but they are still a little vague as they avoid extremes. Understanding real-world situations, eventually, I would attempt to shift into a gear not to be used due to fatigue or general inattention.
