There is always a tradeoff. A lower top tube would require more weight and material for the same strength and stiffness and water bottle space.

64ish. Although I have a hard time believing a couple degrees difference over a foot of radius from the steerer would be making enough difference with the amount of overlap there is. I think it's just oversight.
~5 degrees difference would make up ~1 inch of overlap at 12" from center. About where the levers are.
If you've got 6 bikes there within arms reach, curious what the longest and shortest headtubes are. It's 120mm on this bike, and the top tube forming is pretty much flush with it.
With aluminum frames, this wasn't as much of a consideration since there had to be room on the headtube for welds, so the miter would intersect lower.

100 to 145 mm.
4 (the carbon ones) are flush. The metal ones aren't. Spacers vary from 10 to 25 mm and 12 to 27 mm rise bars.
Perhaps my sarcasm was a little subtle, but the fact that you didn't recognize 12" as sarcasm kind of proves my point.
Can you help me understand the real-world problems you experience with a head tube you think is too short. What's the issue using more spacers or a bar and/or stem with more rise? Your steerer needs to be long enough regardless, and you'll have less issues with controls hitting the top tube, better standover clearance, etc.
It's a once a year thing for me but I clean or replace valve cores pretty much every day I work at the shop so the general population definitely had this problem.People really have problems with clogged valve stems?
As Westy said, the length of the headtube and the height at which the top tube joins with it is one of the boundary conditions for torsional stiffness in the front triangle. You'd want it as tall as possible for that case, but there are packaging considerations to be made as well (standover ergos, clearance for controls, clearance for water bottles, etc).
The real issue is that a long steerer tube and short headtube looks goofy as fuck. Depending on the kind of spacer, you may have issues with the headset loosening more over time with a polarized setup like that.
Speaking of goofy, from a aesthetic standpoint I am glad these days are behind us. I'd rather have my bars hit the top tube than have to look at all the swoopy toobz bullshit
dammit now you made me go look. my nomad has maybe 1/2"-3/4" of spacers and plenty of clearance, clarence.
Flex is going to be an issue for bigger, more aggressive people no matter what, particularly on aluminum bikes. It's always a challenge to accommodate outliers in size and riding style, and I'm not sure 10mm taller will make such a big improvement in frame stiffness that it justifies alienating the number of riders who don't want a head tube that tall. And as for fine-tuning fit, I personally would rather fine tune with spacers than buy a whole new bar, but ok.
I spent years riding larges and could only get comfortable on XL's once headtubes got a little shorter. (I'm 6'1", around 195 lbs., with ape arms. Ironically, I'm now back to looking at larges since bikes have gotten so long.)
Just sayin', count me as one of the increasing number of folks who prefer to choose a bike size for reasons other than head tube length.

Aesthetically, kill it with fire.
Balance of structure and clearance/packaging, does the job.
Manufacturing - nightmare (probably).
Probably makes little difference once you go to carbon or use hydroforming. A mold is a mold.
Alignment tooling for that with hydroforming would probably be a bitch.
Too many spacers will cause the HS to loosen
regarding this flexing steerer tube issue and if you can't or don't wanna go the dual crown way, an Intend Stiffmaster upper cup seems to be a neat solution
I have one.
Not because I thought my setup was flexy but because I thought it was an interesting idea and I wanted to know if the difference would be noticeable.
The only time I notice(d) it was standing up cranking at max power, in that situation it does feel stiffer the rest of the time no difference.
Orrrrr you know...dual crowns.
I was always aware that there was stem/steerer flex on my bike when I had the single crown and that was the reason I went dual crown. One thing I wasn't as acutely aware of however was the big increase in lateral stiffness to be gained. I suppose it makes sense, but it was very noticeable on a race track I've ridden many times that has some very tricky fall line sections with some awkward turns through them. After experiencing the before and after I feel the lateral stiffness gain is a bigger benefit than the stem/steerer gains.
In motorcycle racing the frame/fork stiffness grail was chased until they figured out that some degree of flex helped handling and traction. This paraphrasing Kevin Cameron.
That’s in part because the travel of the regular suspension is 45 degrees off from the plane of the ground.
You know what's wrong with The Industry???
The word "STOKED"
In every bike review video, or go-pro video, you hear it:
"We're stoked to try this..."
"We're so stoked to get this..."
"I'm stoked!"
...you get the idea.

Subscribing your point entirely. On the bright side, we got rid of "shred" "schralp" and "gnar" almost entirely. Give it some more time and it'll fade away in favor of some other lingo bingo contraption.
i will freely admit to laughing loudly and gleefully when riding through steep technical chunder. apologies in advance.

I believe the while yeeew thing was started by shitty mtb vloggers trying to artificially express stoke for likes.
I do this
I'm sorry
but it's never for innernet likes, it's more just a release because it's either that or I pee myself from excitement like a dog
probably
