Scrod I have the oppurtunity to pick up a Sugino GPS crankset with 170mm arms for cheap. Crankset is 144bcd and appears to fit a square-taper bottom bracket. Would I be able to simply take the two road chainrings off and install a 144bcd track chainring and have a cheap track crankset? Am I gonna have issues getting a straight/semi-straight chainline? Also any idea if I'd be looking at the same bottom brackets as Sugino 75's fit or would I need something completely different?

thanks for any help
