I know most of the literature says don't use the small-small or big-big combinations. Doesn't this generally refer to triples and/or modern bikes with wider spacing? I would think that on bikes in the CR timeframe, with double chainrings, cross-chaining would not be as big of an issue, unless the chainstays were really short.
I only have 12 speeds, I'd like to use them all.
