Is There A Reason That Mountain & Bike Handlebar Diameters Are Different?

I understand the lack of compatibility between brands, brake pull, etc... but that being said I have seen brifters on flat bar bikes. I have also seen mountain style brake levers on the flat portion of road bars in addition to the brifters. How they got this to work, I don't know.
I saw a video recently on Youtube where a bike mechanic explained that very thing - people want to turn their road bikes into gravel bikes but they can't because there is not enough room to fit the tires. There is just no room for anything but the skinny road racing tires.
I thought thats kind of dumb as well, it limits the versatility of the bike. I have an old Trek 750 Multitrack and it as 32mm tires but can take all the way up to something like 45 or something crazy. It has tons of room.

No, you're wrong again. I even provided a link in my previous reply. Shimano road and MTB is compatible - Di2. Read, or watch the linked video here once again:
https://www.cxmagazine.com/mechanica...train-shifters
Thank you for admitting that your claim is only based on your limited experience working at a co-op. The reality is that the market is much different than you describe it.
Yeah, you're missing the point. You don't need mountain shifters to actuate mountain derailleurs with Di2 or AXS. They can work with road shifters...

I can almost guarantee you that within 5 years, we will see 1.5” steerers, 110/148 boost spacing and 35mm handlebars on gravel/road bikes.
I still don’t understand why anyone would expect road bars and mtb bars to have the same diameter, for all the reasons stated by others. What is the use case?

I don’t see how this is relevant to the thread. The thread is discussing using road shifters/brake levers on flat bars and trigger shifters on drop bars, which I have never seen done before.

Road brake levers work a bit better on flat bars but the brake routing is funky. If you are trying to use aero levers, the brake cable makes a very tight turn at the bar (or just flaps around to catch on everything. You could use a integrated shifter but, again, the cable routing is funky.
Generally, shift and brake components work best on the bars they were designed for.

Sorry, not interested.
However, we can keep discussing how modern mountain and road shift and brake levers are compatible with the drivetrain and brake components, if you're still interested in learning more about that.
The same goes for SRAM vs. Shimano market share and how one guy's opinion based on his alleged co-op experience is at odds with the true numbers.
Just let me know.

Now granted, most of the bikes we see are older bikes but not all of them are. We see a fair number of newer bikes as well. The vast majority of new bikes are Shimano equipped. Maybe that will change as SRAM grows but that’s the future. I’m talking about past equipment.
I also don’t live in a vacuum. I know the market and check out new bikes on a very regular basis. SRAM is making inroads into Shimano’s market share (50% of the total market) on the high end but Shimano still has most of the market. SRAM has about 35% of the market. I don’t say this with glee. I have bikes with both Shimano and SRAM. I have bikes that are completely Shimano free (it wasn’t that easy to do when I did it). I’d like to see SRAM gain more of the market just to have some innovation. Shimano is kind of stodgy and don’t generally make components cross compatible.

Not sure if you are making fun of me or not but thats ok . My post seems to have drawn the ire of many. Oh well as they say.
I understand the lack of compatibility between brands, brake pull, etc... but that being said I have seen brifters on flat bar bikes. I have also seen mountain style brake levers on the flat portion of road bars in addition to the brifters. How they got this to work, I don't know.
I saw a video recently on Youtube where a bike mechanic explained that very thing - people want to turn their road bikes into gravel bikes but they can't because there is not enough room to fit the tires. There is just no room for anything but the skinny road racing tires.

Thanks for correcting your erroneous "SRAM's market share is "fairly small." bit.
To learn more about how SRAM has taken away significant market share from Shimano, you should study how SRAM was first to market with 1x in the MTB segment and has been eating Shimano's lunch on OEM specs (which helps drive significant repeat business, further strengthening market share).

Nowhere in the AXS link is a battery or software upgrade mentioned. Because you don't need a compatible battery or a software upgrade to make it work, as you claim.
Here is the AXS link so you can read it:https://blog.3t.bike/2019/09/12028/g...s-drivetrains/
Again " they're only compatible with a lot of tinkering and the use of a special battery and a software change." is false.

XTR Di2 Firmware Updates
Before you can think about mixing Shimano’s XTR Di2 MTB derailleurs with the company’s mechanical brake or hydraulic brake road Di2 shifters, some firmware needs to be updated using Shimano’s eTube software. Namely the battery, SM-BTR1 for external or SM-BTR2 for internal; they need to be on Version 3.0.10 – at the time of this article.

Known Incompatibilities
- Road Di2 derailleurs and XTR Di2 derailleurs cannot be mixed and matched. For example, you cannot use a Di2 road front derailleur in conjunction an XTR Di2 rear derailleur – Shimano blocks this with the system firmware. Some people will claim it can be done, but we’ve yet to see a working example.
but until now that meant mechanical shifting or a cobbled-together Di2 setup mixing road and MTB parts that Shimano doesn’t want you to mix. So every firmware update is a potential game-over for your shifting.
And, by the way, just because you can show that one part of Shimano’s electronic systems force road and mountain systems to work together (barely), what about the rest of the Shimano line? Are you saying that just because one system works, the others will too? I’d love it if it were true but it’s not. Electronic shifting is an outlier that really proves nothing.

[Nope, I pointed him to the AXS link, he read the Shimano link (which you're now quoting too - please pay attention), and I pointed him once again to the AXS link.
It's right there in black and white, if you care to spend the time to actually read the article. No battery or software changes needed for AXS to mix road/gravel/mtb.

You're moving the goal posts.
Here is your false claim that I replied to:
"modern mountain and road shift and brake levers aren’t compatible with the drivetrain and brake components."
To summarize:
A modern Shimano mountain and road shift systems and brake levers can be made compatible with the drivetrain and brake components with a lot of extra work and probably extra parts.
