Disc brakes future of road bikes?

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

Ask the UCI. It's largely up to them.

Look at the TDF stage wins on bikes with disc brakes this year. Two so far. Not going away soon.

Having said that

I think you will discs grow increasingly popular until the UCI either lowers or eliminates entirely the antiquated 6.8kg weight limit.

Eventually yes, IMO. Tested a road bike with hydro brakes the other day and its very good. Im sure calipers will always be around, but Im convinced the market will shift towards discs. Its just too good to be ignored.

I would happily add half a pund to get hydro discs over calipers.

Disc brakes are the future. For those who care about performance first, there is no other choice. And let's be honest -- the ambulance chasing lawyers have a bigger say on this than we might like to admit. When you have a braking system that is so obviously better than the traditional system, the plaintiffs' lawyers are going to sue any manufacturer blind who persists in producing and selling rim braked bikes. EVERY case where a rim-braked bike runs into something -- a stopping or right turning car, for example -- it will be argued that the inferior brakes were to blame. Rim-braked bikes will quickly be deemed a "defective product" in the eyes of the plaintiff's bar. (And they will make a LOT of money on that argument. Maybe I should change careers!) A manufacturer would be foolish NOT to shift as much product as possible to disc brakes.


Will rim braked bikes become extinct? No. After all, I think it's still possible to buy a bike with cantilever brakes -- by comparison, little better than dragging your feet on the ground. But they will become more and more difficult to find.


The UCI is being dragged screaming into this. This issue has caused them to lose a lot of their previous influence.

Catch being...cheapo disc brakes are as bad or worse than cheapo caliper brakes. In some ways they are worse, cheapo caliper brakes you can at least buy Kool-Stop pads/holders and get better braking out of...I'm not aware of such a kludge for cheapo discs.

Which of course matters....since the market for cheapo bikes with cheapo parts is far larger than the market for nice bikes with nice parts.


As for the UCI...yea well they're a bastion of conservatism...what is unusual about the whole thing, is that the sponsored riders who are employees of the manufacturers (basically) are freely voicing their opinion publically against the manufacturer/sponsors product. Here in the USA, your employers would haul you into the Star-Chamber for that kind of behavior.

Marcus Ti, plaintiffs lawyers don't care if the actual product really is safer. All they care about is whether they can argue successfully that the rim brake design is inferior. In this case, it's an easy argument. They are not in the product comparison business. They're in the money business.


They love the luddite who makes arguments like, "but BAD disc brakes . . . !" Their response, "But sir, you didn't offer this poor woman even the CHOICE of bad disc brakes. Her face is permanently disfigured because YOU forced her into rim brakes that you KNEW were an inferior design." Money machine.

For all we know, the pros are following orders when the few are making the silly safety argument. Once their bosses are able to get their disc braked product fully in the pipeline, the spurious meat slicer arguments will go away.

After getting tired of replacing so many brifters, I downgraded one of my bikes back to DT shifters. They are cheaper, lighter, totally bombproof, more durable, easier to maintain, better looking, and are easier to skip across gears than other shifting systems. The only drawback they have is you have to take a hand off the bar to shift. But if you don't shift lots, that's a total nonissue.

I'd say once prices fall a bit more (hydro discs at the Sora level), once thru axles are standard on every frame (making it easier to align the rotors), once they make the bleed process just a bit simpler (it's already not bad), and once they settle on a universal mounting standard (flat mount, probably) discs will be standard. We're already well on our way, I wouldn't buy a new road bike without them. I think hydro discs are simply better than rim brakes. MTB has been there for years, even inexpensive MTB hydros like Deore are really good these days.

Maybe I'm wrong here, but I've never heard of drum brakes being blamed as the cause of a motor vehicle accident, despite being inferior to discs.

Same argument, and it seems not to work.

Had a set of Tektros on a 29er where one of the brakes just never would act right. Took as much hand force as a v-brake bike. Miles away from my Formulas, or even my Deores.


Their only merit was that they didn't degrade further when wet.

I'm waiting for suspension forks on my road bike. They were the big news in 1992, and the bike industry were pushing them as the 'must-have' item. Why did they never take off?

Second: I want a suspension seatpost on my carbon bike. Carbon is a firm ride, and a suspension post will take a lot of the butt sting off my long rides on pavement.

I worry about getting a bike with disks and getting sued as a result of a collision in a group ride. I hit the binders, and the rider behind with (inferior) rim brakes plows into the rear of my bike, and goes down. This might cause a mass pile-up involving multiple riders and tens of thousands of $ worth of gear.

Plus the risks of getting sliced...

The average recreational rider doesn't need disc brakes. But need has little to do with it. Look at all the do-dads and gizmos on modern cars--rear view cameras, navigation systems, heated mirrors, heated seats, etc., none of them necessary, but what is necessary is for the auto manufacturers to gain/keep market share, because if their competitors have it you can damn bet they better have it too. Disc brakes on bikes are in the same category.

I have a cx bikes with disc brakes. Yeah, they stop better in the rain, but it doesn't rain all the time, and most cyclists don't ride in the rain anyway. I never choose to ride that particular bike because it has disc brakes.

My next road bike will probably have disc brakes, but only because I sort of like the look of them.

They would be more popular than they are now if the manufacturers had just paid a little $umpthin' $umpthin' under the table to the right people.

You're too young. Back in the 1960's, it was a thing. Then, almost all vehicles switched to discs.
