I originally posted this reply on the wrong thread........When I built up the '83 le tour frame I mention earlier in this thread (frame only weight: five pounds, eight ounces), I "modernized" it with a SRAM 9speed cassette (11 x 32), a used XT rear der., a touring crankset I found at Nashbar (48 x 38 x 28), 105 front der., new 36-spoke 700c wheelset with freehub (Nashbar closeout), BMX brakes on the rear to reach the 700c rim, 9speed bar-end shifters, aero brake levers, and Brooks B17 saddle (the saddle is hardly modern!). The old parts I used are: frame, fork, front Dia-Compe dual-pivot brakes (came off an '84 le tour, the '83 had center-pulls), headset, stem, handlebars, and seatpost. Just like with the bare frame, I weighed it when I got it done: 25 lbs., 6 ounces. Obviously, the parts I used aren't particularly light, but for a commuter/tourer, it's fine. I have no idea what it weighed with all of the original parts on it, it had not been a complete bike since about '84. Since I weighed it, I've added Gizmo clamps and water bottle cages, fenders, and a rear rack.
