Here's one of my bikes. '92 Cannondale R1000, originally was a full Mavic groupe, but this one got some weight weenie substitutions - Campy Record tubular rims, Hi-E hubs, American Classic seatpost, Avocet Ti saddle, Tioga stem, Scott bar. Weighs 17.8 lb. I plan to get it sub-17 lb, via a White Industries Ti bottom bracket, all-carbon fork, threadless headset and stem. I don't actually want to go threadless but losing the alloy steerer will save significant weight. The crank is a real pig too, I think the later starfish version (Mavic 631/2) is 50 g lighter.
