hello,

can someone enlighten me as to what is the reason behind a chain line that tapers toward the chainring instead of the cassette?

really low gearing? does it have to do with the rear derailleur?

the bike below isn't mine. just to illustrate the kind of chainline i have most of the time... using the middle 38t chainring (i have a triple). the chainline gets mostly parallel when using the larger chainring.
this is a large aesthetics matter for me, but i'm planning on switching to a compact crankset and would love to have a chainline that tapers toward the rear.
my rear derailleur is deore.

thanks.
