Don't yet have a camera, so can't upload pics, but I guess my main bike quaifies (
)
I've built it up starting with an '05 Giant Rainier (mid-level xc hardtail) -- what's left of that is the frame, (rebuilt) headset, and f/d.
The rest: Sram x9 gripshift, midcage r/d, 12-25 road cassette; BB7 brakes w/ SD7 levers, Shimano lx crank and 520 pedals; Giant carbon seatpost/Selle Italia; Mavic 717disc on XT hubs; Panaracer Pasela TG folding (1.5); a nice, 'new old stock' Marzocchi MX Comp air fork (one of the good ones, made in Italy circa 2005, weight about 3.5lbs).
All up: bike is just under 25 lbs, v. fast, and rides/handles perfectly for my needs.
