That is interesting.
I did a little checking and found that a 46t-24t Alfine 11 setup would yield a gear inch range of approximately 27" to 110".
This is wide for a road bike, but a bit short for a hybrid and well short for a mountain bike. Many hybrids have a lowest gear of around 22"-23" gear inches. A lot of road bikes don't go under 30-31, or even higher.
I did read that Shimano does indeed recommend that the lowest crank/cog ratio should be 1.9. Else you are out of warranty. I've seen where people have gone with 46-28 combos in mountain bikes and just taken their chances.
I am surprised that the only real difference between the Alfine 8 and the 11 are the addition of more top end gears. The low end is approximately the same.
