I'd be perfectly happy on a steel tube 10-speed from 1975 if I was allowed a modern click shifter and modern disk brakes. Steel frame bikes are really nice, and 10 gears is more than you need anyway. Steel frame bikes from 1975 won't win you a modern race, but they won't be far behind.

Yes Steel is Real but the last Tour winner on a steel bike was in the '90s (and that's the subject). Bikes weigh no more than 8kg. The weight weenies are winning, carbon everything down to brake rotors.

Doubt you'd see a bike equipped with anything else at the Tour.

At the top level - which is pretty much the definition of a tour winner - grams make the difference between a win and loss, so of course they will not be riding steel.

I'm not at top level and never will be. If I want to go faster there are many things I can do that are more effective than playing what my bike is made out of.

Somewhat. UCI has a minumum weight (6.8kg) for bikes and often teams have to add weights to their bikes to hit the minimum limit. You easily get lighter bikes but your bike needs to be 6.8kg to be race legal. It certainly limits how many bits and bobs on the bike get switched over to using titanium or carbon fiber.

I'm not that deep into racing, but I'll guess that teams still want to be way under that weight so they can strategically place weight where they want it.

They may want it, but the technology only recently converged to the point where you can have an aerodynamically optimized bike under the limit weight. Before that there were special lightweight ones for the mountain stages and heavier but aerodynamically faster ones for the flatter stages. Most teams still got these two, plus of course another bike for time trial, because time trial stages are not mass start and the bikes and rider positions can be even faster and less safe there.

Some bikes are over the minimum weight, by a wide margin, and rode by the race leaders too.

You can make a steel frame bike which will be lighter than the UCI weight limit with modern technology. It's just nobody cares to make one because the "unracer" crowd who believe steel frames are magic, won't be spending a couple grand on a light steel frameset and the actual racers are fine with the carbon frames, where it's much easier to control properties of different parts of the frame through fiber layout.

What I want as a non racer is different from what racers want so I prefer a cheaper steel fram, as the gains from an expensive one won't be worth it.

of course the above is a guess, if someone makes such a frame I may try it and decide it is worth it.

Non-racers appreciate light and comfortable bikes too (if anything it's much easier to load a 20 pounds bike on a car/bus rack than a 30 pounds one), this is why carbon is now even in the midrange consumer segment. And with the tubeless tires even on the road bikes nowadays, the magical suspension properties of a steel frame are hardly noticeable over the effect of lower pressure in the tire. So I don't think steel frames are ever coming back.

That's not really true, if you can make a ultralight full-featured steel-framed bike there will be buyers. There is a not so small crowd of "weight weenies" and/or steel frame fans willing to spend big.

How do you know? Do you believe weight weenies are only into steel and this is why they don't buy ultralight carbon bikes (there are few under 3kg carbon/composite bikes that had been made but nobody bothers with industrial production of 100K bikes somehow).

3kg bikes are not practical. But I'm pretty sure a complete modern (electronic groupset, disc brakes) circa 7kg steel bike would find buyers, especially as titanium bikes still do find buyers even at prices and weights both higher than comparable carbon bikes.

You could buy a 5.42kg steel bike with a carbon fork in 2019 https://www.bikeradar.com/news/worlds-lightest-steel-road-bi..., given that a regular steel fork is about 800g, even if the original carbon fork is 0g, you can throw in a steel fork for total 6.2kg. Disc brakes instead of rim brakes would be another 200g. Something tells me those don't sell very well though and the company had not been updating this model ever since. Looks like they've done it for publicity.
