my 61cm lugged steel bike (tommasini tecno) comes in at 21.5lbs (according to a digital fish scale) complete with pedals and boat anchors for wheels. with a proper tubular wheelset i could flirt with 20lbs.

that said, i would say your bike is doing very well. weights not a huge deal. my modern aluminum bike is several pounds lighter and i cant tell the difference (other than ride quality obviously)
