What was used on that Panasonic road bike that they showed that weighed about 10 pounds total?

I dunno... If we're going to build vintage weight weenie bikes, shouldn't we make them functional, and able to support our own weight safely? A 16 pound hillclimber that you can ride, makes more sense to me than a 13 pounder that you need to drive to the scales.

I'd stick to 753 or Ishiwata .019 as my frame material then.

The wheels at the shop, I'm pretty sure, are early Weyless instead of Hi-E. Pretty light, although the owner wouldn't put a price on 'em. I can probably brow-beat 'em outta there, but I need to bring my scale down to see just how light they are. I've never seen a Maillard Course; I suppose they were all aluminum? and Record Seta Extras are very hard to come by...the lightest tires at my immediate fingertips are either CX's or very light panaracer TT's. (actually, I think I have just one tt, I carry it around as a spare. If I can find another then that would be a good weight weenie choice, and still sorta rideable...)

Sugino crankset milled front and back and spider drilled through at the normal flute locations. Chainwheel thickness reduced and inner web removed. Lower webs of Mikashima pedals removed. Wall thickness of seat post reduced. Thickness of saddle base reduced and cutouts incorporated. Stem extension drilled and bottom of stem blocked to allow use of super short expander bolt. I have been unable to locate details on the frame tubing other than it was CrMo, double butted with extensive lug cutouts. I believe there was a later version that used a Dura Ace 10mm drivetrain to reduce the weight even further.

Here's an interesting crank for your project, a Topolino:

you are exactly right! I have some topline mountain cranks - a pair on my hardtail, and a pair in reserve. They were some of the lightest cranks on the planet in the early '90's - I suppose that they might compare well with modern stuff. They had a smallish maintenance issue: they broke when you hammered on 'em sometimes (I never broke mine, tho). I'd forgotten that I even used 'em...I'll watch this pair.
