I just weighed my bikes this morning:

2006 Specialized Dolce Comp 44 cm
20.2 lbs with pedals, bottle cages, pump and Terry Fly saddle
29.0 lbs loaded up for long weekend ride! (3 full water bottles, wedge, handle bar bag holding snacks, camera and cell phone...)

2004 Terry Classic 19" (my commuter)
26.0 lbs with rear rack, pedals, mirror, bottle cages, bar ends and saddle
(I did not weigh her with the trunk on the rack)

I'm more than a little stunned at the weight of my 'go fast' bike when loaded up! That's how I rode all my LONG rides this past season including 2 centuries...who would have guessed?
