I think there are valid general points made here, but as usual its straight out with the knives.
note from hayes:
Another thing people don’t think about is, even though they’re skinny, a grippy road bike tire on hot pavement can create a tremendous amount of torque at the rotor and caliper. It’s much easier to lock up a mountain bike tire on a loose surface than it is to lock up a road tire in good conditions.
People are quick to call the guy a fool, not every rider will be riding in the relative flatlands we have here.
The point is surely roadies will want super light weight brakes and although we might have no problems in the Uk, in the Alps and other countries with huge descents they will boil them.
On some long alpine descents even the best rider will have to drag a brake, traffic, road conditions, you cant let gravity take over some time, and not every one has big Kahunnas
I’m nobodys fool and had one of the old early crappy Hope XC brakes fail on an Alpine descent, The front boiled after repeated hairpin late braking and lost all use. You dont get far either on just a rear brake, that went the other way and locked the rear solid, hell of a skid and a luckily just a long walk home.
