There are lots of videos of road guys on long descents with hydro discs where they fade to zero. Lots more braking, at higher speeds, with brakes with enclosed reservoirs, smaller systems(less fluid)...there will be complete brake loss on some of these alpine stages. No standards now as to rotor size, axle type, caliper placement, rotor type and width..gonna be a real comedy central with neutral wheels.
They are a-coming but an answer to a not asked question. Another 'technology', adopted from MTB(ya know, brakes for wet, sloppy, MUDDY races..places where chances of wacking a wheel are high??_MTB)..Win on sunday, sell on monday. Bike makers, with the heavier frames, forks, hubs..more $, more profit!!.[/quote]
What about the more common failure of clincher rims when they heat the carbon to the point of softening the resin? Have you watched TRP HyRd demo of a long switch back decent (simulated) They do about 20 cycles where thy get the rotors glowing red and the small reservoir never gets hot enough to fade. These are cable actuated Hydraulic brakes and do not have large fluid reservoir to absorb the heat.
Does anyone racing downhill use anything but disk brakes? the too hot brake is much easier to solve than the too hot rim.
Most of the heat issues are already solved but you do make a salient point and that is the standards for Pro racing. Hub widths, thru axel or QR, rotor size are much harder to solve but the message from the mechanics are this needs to be solved before disk brakes come to road racing. the change to 11 speed solved a lot of compatibility issues in that a wheel with any standard worked on the other guys gruppo.
