Importance of chain line?
Searched, the track forum, but couldn't find anything too useful.
How spot-on should one's chain line be? We have a (brand new) track bike in the shop, as shipped from the mfg. The crank actually does not look like a dedicated track crank, with the chainring on the outside, and spacers used to take up room on the reverse side where there are shoulders for what would be an inside chainring. Crank has through axle on the drive side; BB is outboard bearings.
As the bike is set up out of the box, chain line is off 4.5mm to the outside at the crank. Is this an issue for track use? I know the SS/FG crowd throw conniption fits about this kind of thing. If the chainring is placed on the inside, it's a bit better, only off by about 3mm on the inside. But my understanding is that this is still considered way too far out to be legit, and besides, makes a farce out of any claim of the bike having an actual "track" crank.
What's the dealio? Would you actual track racers be as thrown off by a chain line that far out from the factory?
I know next to nothing. I am frequently wrong.
