From: you rope
Bikes: a DuhRosa
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

Bikes: yes please.
the chainline might line up with the chainring in the middle position if the rim is centered between the hub spacers... more problematic than that is chain tension in short or vertical dropouts. unless you're lucky as crap, you might be able to magically get good chain tension with a certain gear combo. or you could buy a eno hub... or have trackends welded or brazed on. i would go with the trackend idea.
by the way, do you own a moots?

my answers are -
1 - not likely. you'll have to respace the rear hub axle, shim the chainring on way or another, or both. Once you have chainline right, redish the wheel. you want to get the chainline right so take time to do so.
2 - no, and possibly. you might get lucky. But those half links sure are cheaper than experimenting with different sprocket combos or an eno centric. you can give it a shot before removing all the deraileurs and whatnot. see how close you are. guess.
good luck
