Uma entrevista ao ex-ciclista e drogado David Millar no road.cc em que, entre outros assuntos, ele dá a opinião sobre os discos no Pro Tour. Transcrevo (em inglês):
P:
There’s new technology on the brink of entering the pro peloton, namely disc brakes. What’s your view on disc brakes?
R:
You don’t need them. It’s a stupid thing, it doesn’t matter about the performance because the tyres can’t handle them. So you’ve got a disc brake and you're going down a wet descent, you’ve only got maximum four square inches of rubber on the floor, with the disc brake the tyre can’t handle it. Already the brakes are too good on a normal bike when it’s wet, for the tyre and the amount of surface area you have.
You’ve got about 80-85 kg with the bike with four squares inches of rubber, you’ve to brake gently in the wet. That’s what everyone forgets, you’ve got to brake gently, very gradually when it’s wet. With a disc brake, you're down. I think disc brakes have a place in the sport, but it’s not in the pro peloton. The Shimano caliper brakes are incredible now, they’re bonkers, they’re far too strong. If we have disc brakes, maybe we think about having aluminium rims in the wet or getting better carbon braking surface.
De certa maneira, não deixa de ter alguma razão. Isto que ele descreve pode facilmente acontecer.
Mas também pode acontecer o contrário, nos travões normais. Não ter potência para travar, principalmente em aros de carbono.
