I was bored so I searched for you This is what I found:

"20.8 pounds as you see it here. i added the bottle cage, the front brake, the selle italia gel saddle and a white industries eno freewheel cog to the flip/flop hub. the bullhorn bars with the brake lever are probably a push compared to the stock bars.
an educated guess would put this bike easily below 19 pounds stock."

Another owner placed it as a rough guess at 15 lbs stock, so somewhere from 15-19 lbs stock. Not a accurate measurement, but gives you a ballpark figure to go off of.
