Will you ever go disc?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Will you ever go disc?

I bought a new carbon fiber road bike in March which came with disc brakes. I love the bike and I'm happy with the performance of the disc brakes.

I'm sure it's been said in 10 pages of replies by someone else. I went disc and now the question in my mind is why would you NOT run discs? SO much better in the wet and on descents. I realize there's some top tier competitive rules that prevent it, that's one thing, but for most of us? Man I love them.

It has been asked, and here's the reply.

We refer the manual transmissions as millenial anti-theft devices.

As for disc brakes, I bought my commuter (recumbent) when I was living in Seattle, and I am very glad I went with (cable) Avid BB7s. They work better in the rain than any rim brakes.

When I get my velo in a few weeks, it will have drum brakes on the front.

For a commuter, where weight isn't really that important, I'd go drums over disks every time. Drum brakes work well enough in all weather and require a tiny fraction of the maintenance of disks.

What kind of maintenance have your disc set-ups needed? A tiny fraction of my disc maintenance is, well, so tiny that it might as well be zero, which just isn't feasible in the real world.

We have had very different experiences. I have BB7's on the bike I have used for randonneuring for that last 7 seasons so it has a lot of miles on it in all kinds of weather. The front brake always seems to be getting out of alignment and rubs, so I have to loosen all the bolts and re-align it to stop it from rubbing. I frequently have to fiddle around with the clicker adjustments to balance rubbing and freeplay at the lever which I can never seem to get just right, always either too much freeplay or too much rub. The pads get contaminated or whatever and start squealing, which drives me nuts so I have spent a bunch of time and effort trying to figure out how to get that to stop stop to no avail. Eventually, I give up and replace the pads so they'll stop squealing for a while, which works for a few hundred miles or so depending on the conditions. I've been riding different bikes on brevets this year primarily because I'm so sick of those BB7's.

Ah. Yup, I've had none of that.

Its totally understandable- this happens in industries all the time. Marketing and advertising exist to drive interest in products we didnt know we needed(and often times dont need, but just want).


I have hydraulic brakes on my MTB. I ride that thing probably a dozen times a year and always in dry conditions...its incredibly unnecessary to have hydraulic disc brakes based on how I ride, but its also my 1st new bike in 25 years, so it came with disc since thats what is on a bike with an air fork, 1x11 drivetrain, etc. Discs dont help me around here...at all. Even the most technical singletrack in the region can be ridden perfectly fine with V brakes since its only ridden in dry enough conditions to not ruin the trail.

I will build a gravel frame this fall to replace my current gravel bike and itll have disc brakes. Right now i plan on QR discs because I dont think I need a massively stiff 44mm head tube to handle a TA tapered fork. I want disc brakes because I am curious if its any 'better' than my canti brakes that have kept me safe all these years. I doubt itll be better, but I still want to see because I have an itch to build a frame.

I just built a road frame last year and it has calipers since I dont choose to ride in rain storms and dont have descents that make caliper brakes feel dangerous. All the rest of my road frames are from 1990 or earlier so no discs there. Perhaps I will move to disc brakes on my road bikes, but i cant imagine itll be soon.
With no interest or need to buy a new bike from a shop, change will come slowly.
Both your replies are incredibly specific and anecdotal. I haven't even ridden the MTB in the rain, and I know V brakes won't cut it after the first few minutes. I'm not even a downhiller either. Modulation is super easy on disc, its not just the speed and angle of descent, it's the terrain.
Also it doesn't take rain to make discs better, morning dew will make the first few moments of a decent hairy enough to warrant discs. Good brakes are there for a reason, you may not see the value in not having to wait around for your rims to dry on the first few rotations, but let that sink in as you repeat that statement a few times.

I still have friction shifting on my TT bike, and no disc brakes on any of my road bikes. But I have disc. brakes on all my trails bikes.

Of course my reply was specific and anecdotal- I even said as much in the first sentence where I acknowledge disc brakes are beneficial in certain situations. For the situations I have been in, I haven't wished for disc brakes.
That is clearly me saying they are situationally beneficial and the response is obviously anecdotal since, you know, it's about only my experience and need.

I probably dont ride fast or aggressive enough for there to be an issue if a couple wheel rotations happen before the good braking starts.
Let's go with that.

I feel I ride fast enough and aggressive enough for there to be an issue, but I still haven't ever have one. Tire contact, though, I've had lots of issues with that in the wet (and dry).

This is really the issue. Tire adhesion will always be the limiting factor when it comes to braking. In terms of significance, the ability of the tire to grip the given riding surface, at the tire patch, far outweighs clamping power and (oh brother) modulation.

BB7's can perform fairly well....for a mechanical disc (low bar). I have found that I have to pair them with Yokozuna cable housing to generate enough power with them to get adequate performance.

This said - mechanical are not hydraulic. Hydraulic will compensate while mechanical won't. Whole different ballgame. That said - poor compensation in hydraulic setups leads to all sorts of centering and rotor rub issues. A non-starter for a true roadie.

Everybody who's used disc brakes and instantly realized they were better - look at all the "I won't go back" reported in here - is just hallucinating? No, that's not it. In theory is worth a lot less than in practice.

Disc brakes don't make it any harder, but It can take longer with through-axles, particularly the rear wheel. And since almost all disc brake frames now come with through-axles it may be something worth noting.

It's not a show stopper, but I find it is more work getting the rear wheel back on as compared to a bike with QR skewers. It's just a bit finicky getting everything lined up then threading the skewer through the axle.

As I said, not show stopper, but certainly a bit more work than a bike with QR skewers.

Everybody, meaning those within earshot of you or those un-named who post on the internet? Who's hallucinating here? When it comes to science and reasoning vs opinions of invisible people, I'll take science every time. Care to address my points? I didn't think so.
