The BB is all steel, same with the FW. Wheel axles are steel. The wheelset is a light-ish 330 GL. rimmed tubular set, with not so light Vittoria Rally tubs and Campy Record hubs. They are light, but not really weenie light.
So If I do get serious about shedding some more weight off the bike, I think the 18 pound region would be easily attainable with just a Ti BB, Ti railed saddle and maybe my CLB Compact Pro brakeset. I think I owe it all to the very lightweight Supervitus 980 frame.
