the 9-46 gives a range in between mtb 10-50 and 10-52 but on 11 speeds but has the advantage of being useable with "road long cage" derailleurs (Rival/Force etc.) that work without issue up to 46T.
I run 36x 9-46 which is equivalent to 40x 10-52 /40x10-50 (well to be accurate, it would be 40x 10-51).
When I run the 700c, I have 36x11-46 so with the 9-46, I could run 30x9-46 and keep the same "road" gearing but easy the "off-road" set up. I did not do it because I don't really want to spend too much time on cog 9T but I may consider a 32 ring for Welsh mountain adventures... This would be similar to classic XC GI setup.
