Not exactly what you asked about... What kind of crank do you have now--number of teeth on each chainring and chain line if you know it? Also, what is the rear dropout spacing--130 or 135mm?

130mm spaced frame works best with a road crank, which has chian lines of 43.5mm for double and 45mm for triple. MTB triples are 47.5 or 50mm (with the latter becoming standard) and are designed for 135mm or more spacing.

If you use a crank with an older system (e.g. square-taper), you can adjust chain line to some degree with various bottom bracket spindles, but the newer external bearing-2-piece systems have fixed spindle lengths because the spindle is attached to one of the crank arms.
