When out riding with 1x10, 1x11 and 1x12 riders, its noisy!
Whereas I tend to sit in the big ring (usually 46 or 44t, sometimes 48t) these guys (and girls) clatter up and down, up and down the cassette whereas I still seem to sit in just a few favoured ratios.
At the moment, a 1x system just wouldnt do me any good but thats not to say it will never change.
On my road bike, I use a 30 - 11t with a 53t front end. I had a 50t 'compact' and it was too bloody small! But then its flat around here and the one hill that has a nasty step in it can be tackled with a stomp and a 30t/ 53t combo on those non headwind days.
So, I can see why but its not for me, off-road around the Peaks and Moors its never been an issue
Yet.
