Even if they could drop two teeth on the rear, or even just one. I figure the closer they can get the better.
If a 57 tooth rear would fit, it would make a ratio of 2.375/1. Thats pretty close.
A 58/24 combo would make a ratio of 2.417/1. Not as close but still closer than the 2.458/1 ratio that the 24/59 combo makes.
