So it's never really been the range, its more that there are fewer gears on a 12 spd cassette system period. And it's not like there's a plethora of different 12 spd. cassettes available, the Shimano line has 2 and all are oriented towards 1X systems.....
I have never seen a cassette with a 51 tooth big sprocket, and until your post I was unaware they made one. I thought that the race for giant cassettes was still in the 40 something teeth range. Thanks for enlightening me.
When you say
"So it's never really been the range, ...", how many years has that wide a range cassette been available?
