Weighed my Kilo today, with a luggage scale. 20.66lbs. Size 55cm, all stock, with only the front brake on.
In retrospect, my size 61cm (hand me down, made to work) specialized secteur, weighed in at 21.22lbs. aluminum frame, carbon fork (aluminum steerer).
Was surprised at how light the massive secteur is.
The kilo will be closer to 15lbs when done, as per manufacturers weights +5%. post wheelset, that is.
edit: also, I guess the UPS guy needed to use my torque wrenches for a couple days.... <__<
