The fork weighs 872 grams (1.92 lbs). The front frame section weighs 1156 grams (2.55 lbs). The headset, including quick release, weighs 246 grams (.54 lbs). I couldn't weigh the rear frame section because my scale only goes up to 5 lbs! So (several days on, hence the edit) I weighed it at work and the rear frame section is 2291 grams (5.05 lbs). In sum, the frame is 3.447 kg (7.5993 lbs) and frame, fork, and headset together are 4.5656 kg (10.064 lbs).
