Many none XC bikers have got rid of a third of their gears anyway by ditching the big ring so I am not sure why we need more gears when behaviour suggests want want fewer.
I can see the logic of 2×10/3×10 systems for racing and riders doing long tarmac/gravel sections. But I have been pleasantly surprised how well my HT with 1x system (32/11-34) works for riding the hills and woods of Somerset, and I’ve noticed more of these setups on the trails. The big manufacturers don’t seem to have picked up on this trend. Which seems odd.
I’d like to see Hope bring out a dedicated complete 1x system with: cranks, single ring, BB, Cassette, and chain guide as I think it would sell like hot cakes in the UK. I think they are quite close, but wish they would hurry up!
I do take the point about the usefulness of a granny ring on big-days-out on big hills, though.
I’m this -> <- far from changing my FS to 1x, but keep chickening out.
