My 44cm Ruby weighs 16.2 lbs with pedals and bottle cages (compact double). I guess I could shave a lb with lighter wheels (serious $$) and brakes (has 7700 dura-Ace, not light but good feel).

The commuter I ride to work, a Fuji Newest 3 (XS) frame with my parts (compact double) and rear rack weighs 27.6 lbs (without the trunk bag).

I've got two mtbs, a Giant Anthem-W (S) with a lot of upgraded parts, 27.5 lbs with bottle cages and pedals and my S-Works Safire (S) weighs 25.8 with cages and pedals. It would weigh less but I prefer tires with meat on them over the weight weenie 'Furious Fred' types. This is one place where performance in the rough trumps 200 grams each.
