Sub 20lb steel rides
So my Paletti is currently sitting at 21.5lb and I was hoping for some real world builds from you guys that cracked the sub 20lb benchmark. Modern parts on a vintage bike don't bother me nearly as much as some people. Btw I know it's better to lose the weight off of your midsection first do we can skip that part of the conversation

I have owned, built and weighed a lot of vintage bicycles. Few, and I mean very few, have come in under 20 pounds. And those that did were aluminum alloy, particulary a Vitus, an Alan and, possibly an old Legnano with tubular tires(did not have a good scale to weight the Legnano). Anyway, have a look at some of the weights I took and then published.
That said, I do wish you good luck with your quest to get a steel frame bicycle under the twenty pound mark.

My Raleigh Team Pro is a weight weenie project and I'm trying to use all C&V parts from 1978-early 1980s. 58 cm frame, 753 tubing.
Currently 19.3 lb equipped as follows:
Campagnolo Super Record crank, derailleurs, brakes, seatpost, headset; Cinelli bars, stem; Benotto tape; Simplex shifters; Regina hollow pin chain; aluminum freewheel cogs; Brooks Swift Ti saddle; Nuovo Record hubs; Fiamme Ergal rims (about 200 g each); thin double butted spokes (similar to DT Swiss Revolution); Tufo S4 Lite tires (tubular, about 210 g each); Ritchey clipless pedals (my C&V thing doesn't extend to pedals).
I'm trying to get it down to <19 lb. I suspect a lighter saddle will get me most of the way there. After that, I'll be looking at some small gram trims: a Ti stem expander bolt, a 3TTT bar, etc. I have not (yet?) resorted to drillium. I passed up buying some CLB aluminum brake cable housing after I calculated it would only save 25 g, and now I regret it.
This is a pic before the pedal and chain swap, and before the new tires.
In general, I think starting with a small frame is a big help. Tubular rims and tires are another big help. And of course, starting with a non-steel frame - vintage aluminum or even vintage carbon fiber - is a big help.

Fixed/Single Speed? Really the wheels can be the next biggest source of weight reduction.
I have a 531 frame and fork that comes in just over 5 pounds. Don't have it built yet because I have a minor frame repair I want done professionally.
Most of the good frame fork combinations have come in closer to 6 1/2 pounds. Only leaves 12 1/2 pounds for everything else to get to 19. Probably easier with modern components.

This is boring. Who has the heaviest Varsity or Free Spirit? As noted my Super Sport's freewheel, crankset, and pedals together weigh nearly seven pounds. How much could steel wheels and thorn proof tubes add?

In the early 1970s the only sub-20 geared road bike I recall seeing was A. D. Stump's personal bike, with his signature black chrome hand built frame. It didn't hurt that he was a little guy with a small bike that did not need to support a lot of weight.

I'm not a weight weenie by any means but sometimes less IS more! Here is my 1991 Sancineto, a semi vintage, nuovo retro, retro mod or whatever you want to call it. It comes in at 19 lbs 10 oz without any serious effort at weight reduction!
1991 Sancineto Road Bike | The Utah Randonneur
It was weighed without bottle cages. Apologies for the garage door pic.

Now that's what I'm talking about! Beautiful bike! There have to be more of you out there that are below the 20lb mark

My 60 cm PSN-10 "resto-mod" came in at 19.71 pounds. That was on the LBS digital scale, without the seat post bag and water bottle. I am not a weight-weenie and was focused on function. This configuration was for climbing, and included a fairly heavy 12-36 rear cassette.
FWIW, my original PSN-10 weighed 21.8 pounds this morning, with Brooks Pro saddle and single cage.

It's not modern and not quite C&V yet either. It is a sub 20 pound steel bike as requested by the OP. I built up a '97 Lemond Zurich and it came out to 19.4 pounds ready to ride with pedals. Most of the weight savings is in the wheelset. I built a set using Kinlin XR200 rims. I put Vittoria Diamante Pro Light tires on with lightweight tubes too. All in, with wheelset, tires and tubes it's 1878 grams rotating (not counting cassette). The difference is measurable when climbing. Other than the wheels and tires it's pretty standard stuff. Shimano 5500 series derailleurs & brakes, 6500 crankset, new Shimano 10 speed DT shifters, Nitto 115 bars, Flite saddle and so on. It rides very nice and climbs quite well. I wanted a bike with a classic look, smooth ride and good performance. I'm really happy with this one. Here is a picture before I built a set of light wheels for it.

My son's AD Inter10 weighs in at 20.4 lbs with 700x35 Ritchey SpeedMax tires. Of course, it is a single speed...but he likes that his friends with high-zoot bikes can't believe how light it is.

incazzare.
My Colian weighs in at something like 22 lbs with a modern 10 speed Campy group. I'm sure with lighter wheels, tires, and a group that used more CF / Ti I could make it lighter, but it feels pretty dang light as it is.

It's surprising how much difference there can be from one digital scale to another. That's why the produce scale at your local grocery store check-out stand has to be certified every year, and I would guess that those scales are considerably more sophisticated than the ones we buy at the bike shop or the cooking-supply store.
If you don't like your bikes current weight find another scale!
