I'm building my first fixie and have discovered that my chainline is not the ideal I had planned on while choosing my components. I assumed from the info I culled from the web and the places I purchased my components that this combination would give me the perfect 42mm chainline.
Here's what I've got:
Sugino RD2 cranks w/ TA Alize 48T 1/8" chainring
Sugino 103mm bottom bracket
IRO "Dark Matter" wheelset with Surly 17T 1/8" cog
The chainline at the cranks measure 49mm. This is without the crank bolt, but I doubt that it will suck it in that much. I also know that I can run the chainring on the inside of the crank spider but would rather not(I'm a bit of a perfectionist and that seems like a cop out). A friend of mine has a Surly Steamroller Complete with the same BB,cranks(chainring on the outside), and cog as I've got and his chainline is straight as hell. It was my understanding that the chainline was independent of the frame...
Any advise would be greatly appreciated
