chainlines @_@
um....
i have spent some time reading sheldon brown's chainline stuff....
and im still confused @_@
so lets say i have a formula hub and soma fixed cog, which sheldon suggests creates a chainline of 42.9....
if a crankset is listed as 42 with a 110 mm bottom bracket....what would the crankset's chainline be with a 107 mm? would it then be 39? or would be like, 40.5 (im guessing that because the spindle length is divided in two because its on both sides)...
