bike on the operating table is 1999 Fuji Finest cromo

it has short slanted dropouts (130mm spacing) and triple shimano RSX crankset

I plan to:

-put big 46t ring in middle position of crankset
-run 18t or 17t cog



My question is:

-will the chain just line up if I get use the middle chainring position? would i have to tell the wheelbuilder to dish the wheel or would i have to move the BB laterally somehow?
-anybody know chainstay length of the bike and whether the 46/18 or 46/17 would work?... if not, would a 1/2th link be able to give proper chain tautness?



looking forward to getting some excitement out of the bike again
