Dave, seems weird, I understand the index is in the brifter, so a 9sp MTB rear derailleur could be convinced to jump 10sp. But only if the cassette were to be a 10sp.
I’ve seen Ultegra CS-6700 max at 12-30.
So, specifically what parts would you suggest for cassette and derailleur if I were to need beyond the 30T I’m planning for?
Thanks
