I have a 2001 Marin Treviso TIG welded from Steel Deda tubing. it has a 350g carbon fork and mostly alloy parts. a 1400g wheel set (alloy yes) with sram red and dura-ace 7800 cranks. It's weighs about 17 lbs, I could shave that with a lighter post (thomson elite isn't the lightest) saddle and pedals. Probably get it down to 16.5 if I tried. Oh an it's a 61cm frame.
