A quick fag packet calc suggests than a 10-44 cassette actually comes pretty close to matching the overall range that my old 2×9 managed (11-32 + 36/22, i.e. You can either have the same bottom or top ratio depending on weather you prefer a 30t or a 32t chairing, and give away about two tooths worth of extra gear at the other end… So 10-46 might just do it.
Like I say same overall range, obviously not all the same possible ratio combinations, but as people often like to point out due to “duplication of ratios” there’s probably only about 12 to 14 useful gears in amongst the supposed 20 a 2×10 drive offers, I don’t reckon 11 sequential gears is such an awful compromise set against that.
for my own part In have learned to love a lower range shimano 1×10; MTFU for hills and accept “spinning out” on the odd boring flat bit…
Different strokes for different folks innit…
It’s not like multiple ring setups will vanish, flogging extra parts to the luddites is still profitable… 😉
