Proper alignment between front chain wheels and rear sprockets becomes 
more critical with a shorter chain line, which makes things more 
difficult when using non-standard components.

A long chain line in combination with a idler tensioner (e.g. Easy 
Racers) or a mid-drive can allow for chain wheel and sprocket 
combinations that would not work on a short chain line unless custom 
derailers (sic) were used.
