Sure you don't have to do hard stops to get full bedding in, but it is going to take longer.
I took his point to be .... don't go bombing down a hill to see if your brakes work yet.

Ha! I guess I figured that went without saying, but perhaps I should not assume that.

Disc brake road bikes will soon be the norm.

I ride a variety of bikes with various brake set ups. I am glad to have discs on my MTB. It's nice to be able to finesse the brakes on rough terrain with one finger while I keep a firm grip on the bars with the other four. I rode and raced MTB rim brakes for a long time before I went to discs and a never wanted for more power that I got out of my V brakes. The advantage of the discs to me is modulation rather than power. I have ridden road bikes in a variety of conditions and have never found my caliper brakes lacking at all. I am trying to envision a situation in which the modulation advantage discs offer would come into play. I am coming up blank. I can however envision an emergency braking situation in which I grab too much disc brake, lock up the front wheel and eat it. I have ridden motorcycles for decades and have had a few get-offs where I grabbed too much front brake. I am not sold on discs for the road. Could they be a nicety? I suppose. They are far from a necessity though. I reckon I need to get skilled at disc brake set-up and service, because if there is one thing I have learned about the bicycle industry is that it will change, and this change is on the way.

I also found them to occasionally shudder when it was very wet, the modern ones probably don't do this.
The better brakes don't while the cheaper still have issues. You get what you pay for.

I'm not talking about offroad

I mean rocks the size of your big toe, loose sand and washboards)

Umm sounds like off road to me.
I see how that would be confusing but for us that's just regular gravel roads. It's manageable with tires sized 30mm+ but not much smaller.


I have not had any issue with cantilever setup along with many others and it is very presumptuous of you to suggest otherwise. I run 41mm knard tires or 38mm crossroads (depending on where I am going to ride) on my current CX so maybe that is why mine are fine but I think otherwise. currently using avid shorty brakes and modulation is great.
What a coincidence, my rear brake is an avid shorty ultimate and like all cantis it sucks big time even with Kool Stop pads, compressionless housings and a DT Swiss machined rim surface. Or rather, it sucks bad when compared to my discs. It's not a bad rim brake per se but even with the most powerful configuration (since you can set them up either for power or clearance) with the yoke wire 1mm away from the fender top it's still severely lacking in power.

I have a road bike -for the road, a cx - for on and off road, a mtn bike only for off road, and I used to have a touring bike - for roads and light duty off asphalt roads( cx has rack mounts)
My road bike is pretty much do it all so it can handle roads, gravel and even light singletrack. My setup would not be possible without discs. I tried something similiar with my rim brake CX a time back and even with the most powerful rim brake / brifter / tire clearance combo there is (mini vee) I found the setup fiddly, grabby and overall unpleasant.


You have me at a disadvantage I guess, I only have slush, sand, salt, grit AFTER EVERY SNOWSTORM. for 7 months Where do you live?
We get that constantly for 7 months, not just after every snowstorm. I live Scandinavia.


Apparently. I love to learn how others do things compare them to mine. If they get better results than I adopt their method.
With hydraulics you need to eyeball the alignment without brake pads and then center the pistons to the disc with a small screwdriver (Ie. hope method)

Sorry it took me so long, was touring.

There are a bunch of rim brakes you can buy that will allow up to 42mm tire.

The problem has never been the brake, it's that bike manufactures didn't design a bike that could fit the tire. The fork and brake bridges were too low.
I addressed this issue before. If you want braking power you can only use short reach calipers whereas long reach calipers suck in terms of stopping power. So then you have cantis which also suck. Vees don't work with brifters etc. etc.

Yes, I have every one of the above brakes in use in my current set of bikes.

And all the while discs offer a solution with little to no compromize

I've used them on a MTB that I switched from cantis to V's. They work just fine, they aren't complex and they don't weaken the cable.

Doesn't take much skill at all. I find them easier to set-up than caliper brakes.

So, has it been resolved? Why don't elephants have tusks and why don't cars have wheels?

That was the debate, wasn't it?

You're seriously saying that a sharp angle that frays the cable doesn't weaken it? Sure, whatever. I remember reading from the manual that problem solvers suggest swapping the cable periodically because the system weakens the cable...

Also while the system itself isn't that complex it adds unnecessary complexity by adding moving parts, possible break points, friction etc.

Think of it as a retro ratchet, it doesn't have to go that far back. OTOH, Fixies have come back with a vengeance.

I don't doubt that. I just need to find someone who knows what they are doing to show me the ropes.

I had travel agents on a bike about 10 years ago, I did have a cable fray where the VERY sharp bend is. That is why I went with the shortys.

Yes they are here to stay alright, and they are tech too, which means that once they are percieved as "acceptable" they will be in big demand by the community.

In the future when you go buy a new bike to replace your current road bike...It will have disc brakes.
