Fair enough, sounds very odd – to go from being able to ride everything on a 46 to wanting a 24, each to their own!
I know it’s a bit of an odd requirement, like I said, I barely move out of the big ring on most rides but on the very steeps and when I’m knackered I would like the bail out option which is why I’ve not gone single ring.
I’ve not tried an 11-36 rear cassette, only 11-34 so you might be right with 26/42 if I got a 36 tooth cassette as well it could work, but I’m loathe the replace perfectly good cranks and cassette when they still have loads of life in them… maybe in a few years when I can’t get spares any more!
my hardtails are all SS at the moment, but I’d never run into the stupid feedback problem there so maybe I should experiment a bit more at some point
