Colnago C59 Disc

I'm quite aware that he (ab)used the brakes. But this is how riders, especially novice riders use their bikes. I doubt the issue of overheating brakes, even of overheating rim brakes (using carbon surfaces in particular) has the attention of every single person that uses them. The same will be true for disc brakes.

Again, I want disc brakes for road bikes, the sooner the better. As long as I'm confident that with proper use, they will be effective. I'm sure that will happen.

that article is not a critique of disc brakes on road bikes. It is a critique of "Ashima’s new and ridiculously light Ai2 rotors" on a single bike. "I built a death trap bike" would be a better title.

Might as well say cartridge pad rim brakes are fatally flawed because it is possible for a determined tw@t to fit them with the pads the wrong way around and eject the pads at the first firm braking action.

I'm turning in my grave (if I was dead), discs on a C59. Worse than sticking Shimano on an Italian superbike !

Me thinks Ernesto has lost his ball bearings now he's turned 80.

Rim brakes are an out-dated antiquity that should have been consigned to the bin decades ago. All the arguments against discs on cycles were used when they first appeared on cars and motorcycles, now no-one would buy either without them. Even his Holiness Saint Lance is a fan (and for all his faults he understands bikes).

Bring 'em on.

Disc brakes, Electronic gear shifting, might as well put an engine in the frame next!

I reckon they're the next big roadie bike trend, but what I think we need is roadie bike specific disc systems rather than small MTB systems. You wouldn't need the same size brake on the rear of a road-bike for example. Maybe smaller rotor up front too.
But the upsides are big, especially in the wet (as long as progressive) and having lighter rims.

Was my first thoughts as well but reading up on it a bit and I'm not so sure smaller rotors are a good aim. Less area to dissipate heat through and creates greater forces at the dropouts...according to what I can glean.

If this is accurate, and I lack the engineering skills to be certain, then small wouldn't be beautiful for road bikes.

That may be correct, I'm no engineer either, but maybe larger diameter with smaller piston assemblies oor something that is designed for the particular needs of road bikes rather than the different application of MTBs. Also they could be more aero and pretty too. I agree that they do seem to put much more energy through the fork dropouts.
