You think rim brake, direct mount will return?

To be honest it's a long time since I had to do anything like that with either road or mtb pads/discs. They just seem to work. I have noticed that the pads are generally larger now than they were in the early days (mtb at least), so maybe they are less sensitive to noise/vibration.

1. The present discussion is about road bikes, not cyclocross bikes. Even before disc brakes, cyclocross brakes used different brakes than road bikes.
2. The people on this forum are not representative of the general bike-buying population. Many are very set in their ways, and they are very vocal about it.

The allure of hydro discs, electronic shifting and tubeless is that it just works (and works better than the old stuff, too). You air the tires, charge your gears (you're charging your Garmin anyway) and go. If something (infrequently) causes a problem, you visit the local shop or a mate who likes fiddling with their bikes.
Half the cyclists I ride with (especially triathletes, heh), prefer to just ride their bikes, not wrench on them. I've ridden with triathletes who are good, but who couldn't shift to the big ring and resigned to riding in the small ring. So I'm like "turn the barrel adjuster out a few turns" and they're like "Turn a what? ". So I don't think that this community is so representative of people who buy and ride bikes.
Personally, I can fix most bike problems and I really like my bikes with mechanical shifting and mechanical discs, but the next bike I get will have hydraulics and electronic shifting because it's really just better, at the end of the day.

No argument that it likely works better, but Di2 had better work better as it's close to double the cost of its mechanical counterpart.

You asked me when was the cycling community against disk brakes. It was when people started taking road bikes and beefing them up with disk brakes (because rim brakes often got gummed up with mud on trails) and knobby tires (caliper brakes often didn't spread far enough to be able to take off a wheel with a fat tire) for off-road racing. The road bike community was against putting those heavy brake systems on road bikes. And I think this community is a pretty solid representation of the dedicated cycling community....the kind of cyclists who pay attention to stuff like this. I'm not for or against disk brakes, I'm just surprised at how quickly the cycling community has flipped their opinions on the subject.

Or if disc brakes were crap, there would have been a huge backlash by now. Something like we are kind of seeing to a certain degree with some press-fit BBs. I just don't see that turnaround happening with disc brakes. Even TT bikes are now rapidly moving over to discs.

The next big thing will be CF rotors @$1k each. Solves all your musical brake problems. I downgraded my track car from CF pads on slotted and cross drilled rotors to ceramic pads but not for performance. Which has nothing to do with anything.

I've got Bontrager Speed Stop direct mount brakes on my 2019 Emonda SLR with XXX2 carbon wheels.
I've got Sram Red22 HRD disc brakes on my 2021 Domane SLR.
There is very little difference in braking performance between the two,
But in comparison to my 2011 Madone with Sram Red22 rim brakes paired with Bontrager RXL wheels (2010's),
performance of the direct mount brakes is far superior.

Do you feel the need to nit pick every comment? I said when they FIRST started making an appearance on road bikes in the cyclocross community, the road cycling community largely rejected them. That is factual statement. Nobody was running disk brakes on the pro circuit 10 years ago and the OEMs weren't putting them on dedicated road bikes. They existed, but were not popular in the road community. We had several long debates on this forum back then and the consensus was that they are not meant for road cycling...mostly due to weight. Since then they have taken over. That's all I'm saying. Not sure why you want to refute this.

How many ways can we think of to start a disc vs rim brake thread? This has to be the third this week. Holy crap...It's a bike. Ride what you like. You are pretty unlikely to burst in to flames for making the wrong decision because there isn't one...

For the next one we should include frame material and tube/tubeless for a trifecta of BF dead horses.

* Both attributes are only better by a tiny margin. Like how disc brakes offer tiny benefits in most situations.

The upside of disc brakes is not revealed in the situations where they offer tiny benefits, it is revealed in the situations where they offer more substantial benefits.

Of course, many of us simply choose not to ride when the weather gets nasty, or we have a bike for those conditions and another one for the nice days. (My rainy/winter bike = disc brakes, which are decent. My dry weather bike = excellent rim brakes. It sure is nice living in the "first world".)

I admit I prefer the esthetics of rim brakes, but that's just vanity, or nostalgia.
I have one bike with dual/single pivot calipers.
One bike with cantilever brakes.
One with mechanical disk brakes (tandem).
All bikes have alloy rims.
They all stop my bikes, even in the wet (eventually - so far tire grip in the wet has mattered more than brake grip, but I'm fairly timid descending when it's wet). To date, I haven't seen any need to replace a perfectly good bike just to get another with disk brakes, with one caveat: I'm glad to have disks on our tandem bike. I'd descend a lot more slowly if our tandem had only rim brakes. It's not so much that the rim brakes wouldn't stop the bike, but they would take significantly longer to stop it, and I'd have to squeeze a lot harder which would make it harder to absorb bumps while braking, which could compromise my control of the bike (the road surfaces around here are not always the best).
I took a ride a couple of days ago on my canti bike, and I took a route with lots of steep descending - including a +30% slope down to a stop sign at a junction with a high speed road (stopping is not optional - very short sightlines). The cantis worked fine, but I admit I'd have appreciated having disks, my forearms would have been much less fatigued.
I'd much, MUCH rather replace disk brake pads than canti pads. Even setting up the disks the first time was pretty simple - centering is certainly easier than it is for cantis. And after that, it takes a couple of minutes to pop the old pads out and pop the new ones back in. From my limited experience, it does seem to be true that disk pads don't last as long as rim brake pads. (Edit: I've not had to buy any new tools, though I'm thinking about getting a rotor truing tool for, what, $15?)
So, I guess I don't really have a strong preference. For a single road bike, for my usage (just riding around for fun and fitness, no racing) I'd probably cheap out and get the rim brake option to save money. If I were getting a tandem, I'd get the disk brakes every time. Weight and aero are factors, but not big ones. A light bike/aero can be nice, but it isn't at the top of my list so arguments regarding weight/aero with respect to rim vs. disk brakes don't move me.
(Note: I don't know anything about hydraulic disks, nor carbon rims, nor racing.)

In 50 years of cycling, I have never wore out a set of rims from braking.
My training wheels (Flo 60 carbon) have more than 50,000 miles on them.
How many miles do disc pads last? Maybe a 1000? I got less on mine. That would be 10-15 changes per year for me. THAT is a problem needing a solution.

I've noticed in cycling, while trends come and some leave, they often come around again, like steel getting more popular again, or when press fit was constantly touted by the big brands being so superior, well, BSA is back.
I wonder if rim/direct mount be the same, after a few years of big brands trying shove disc brake down our throats to point of refusing to make rim brake versions of their road bikes, it will come back in a few years?
What you think?

I'm not sure. But I did some group rides this past summer, and noticed on a handful there was someone who had to stop to adjust their brakes, horrible grinding, high pitched noise. This has happened a few times now, I've had brake rub too, but I just lean over or lean back and adjust it on the fly. I mean, I don't understand the love for disc brake cause rim is well simple stupid and it works. I understand the reasons for disc, but how many people actually riding hard in the rain or flying down huge mountains and needing that modulation? Hell every cyclist I know around here use their trainer when it rains.
I'm strictly talking about road, not gravel, MTB etc.
