People keep saying this, and it keeps being untrue. At high speed you need good brakes, not necessarily disc brakes. Some, not all, disc brakes are good. Some, not all, rim brakes are good. But I will say this-- the strongest rim brakes are stronger than the strongest disc brakes. Why wouldn't they be? They have much larger rotors with much higher heat capacity.
The best bicycle discs anywhere can't touch these rim brakes:
If you're retrofitting disc brakes to a bike that didn't come with them, before first trying quality brake pads and a booster arch, you must be determined to spend more money than necessary to have worse wheels and probably worse braking too.
