As one point of reference, I'm going to paste the component spec. on my Swift from the main thread: Stock crank, brakes, brake levers, and seatpost; homebuilt wheels with IRO small flange 32h hubs, Sun CR-18 406 rims, Sapim 15 g spokes, Schwalble Stelvio 20 x 1.125" folding tires, Dura Ace 14t 3/32" cog (paired w/ the stock 52 ring), Speedplay Frog pedals, Nitto Dove bar (flipped), cheepo 120mm 10 degree rise stem, Terry Zero Y saddle, Minoura cage holder w/ Blackburn Switchback, UN73 bottom bracket, and sealed bearing Shimano headset. I think that's it. Weighs in at 19.5 lbs on my bathroom scale.

Right now I've got Freddy Fenders front and rear, plus a Nasbar front rack/bag on it; haven't weighed it in this config.

I too would be interested in fork options, not so much for weight, but to get a little compliance, if that's even possible with such short lengths.
