IAmSam, Do you have a parts list?
Boyd 28 carbon clinchers are 390g x2
Gran Compe SF hubs are 176 and 224 grams
<<< All City New Sheriff rear, swap stock bolts for Ti, cheap weight weenie roadie front hub w/ ti skewer---would save well over 100g
Sapim Laser butted spokes
Brass nipples rear/alloy front
<<< psh, alloy rear nips as well if we're really gonna do this 
This comes out to 1410 grams claimed but will be well over $1000. Alloy wheels would drop the price and probably lower the weight.
Then I see something like the 1460 gram Wabi Sub 15's for three hundred or whatever they are charging now and just can't justify the price of custom. Wabi's are only 13.2 mm internal width though, but still.
