but the question remains why does this crankset not deliver a decent chainline?
Because, with no offence intended, the fuji track pro is still only an entry level bike, and they have to cut cost some place. So they use a crank and BB that is avalible to them at a good price.
A whole bunch of the oldschool trackies just used whatever with whatever. Every* old track bike I have ever bought had the 'wrong' BB for the cranks. I have bough bikes with miche chaninset (should take 107mm), with BB's of 102mm, 111mm and 115mm, but not 107mm and the old dudes never cared, rode them for years, won races etc etc.
