If you want to find components weights you can either check the man ufacturers site or visit the weight weenies site for more accurate weights. As to what do the fork and wheelset weigh - a lot seriously I had a T3 and the hubs on that wheelset (which I think are the same as the T4s were) are heavy as hell. Fork on my T3 was a DukeXC and it weighed somewhere around 3.75-4lbs if I remember correctly. Entire bike with pedals weighed in around 32lbs AFAIR. Biggest pig on there weight though is the hog if a cassette - PG950 if I'm not wrong, maybe even lower than that - thing weighs well over 1lb.
