Re:
The Fausto Pinarello interview was a joke. High end bikes don't need better brakes he says, meanwhile what is a disc version of a Doggy F8 doing in his line up? Typical self-contradicting Italian, they're the best at it. Poels using typical scare tactics with videos that aren't even his. Most likely he never even tested a disc bike in the off season. I've had my rotors glowing red before, but it takes a few successive switchbacks with short steep straights in between. Do you want heat build up on a rotor, or on your rim where it's a detriment to braking performance and also heating the tire interface? Think about where mass pile ups happen, usually on the flats when riders aren't paying attention, or in sprints. How much brakes are applied in those scenarios? Not nearly enough to burn anyone.
For demonstration sake take out a disc road bike and wind up a 65kph sprint, come to a sudden stop and touch the rotor. If you say you burnt yourself I know for a fact you're lying.
