Are you asking in a ~17″ CS on a 275er is short by current standards? If so
I'd call it "normal" compared to other bikes of its ilk. That said it's short
in absolute terms when you look at the width of an 11 speed cassette and how
far over the chain needs to move in that distance.
If you can space the ring inboard you are tuning the chainline just like using
a ring with a different offset. That will improve the back pedalling situation
in the big cogs. As I buy new rings I'm sticking with rings that have less
offset which accomplishes the same thing since I don't have any spacers in my
crank/BB I can't move the ring over any other way.
