Another pro rider injured by disc brakes - are disc brakes really dangerous?

MBWB wrote:

If the claimed issue is burns (I thought people were claiming disk rotors to be salami slicing machines!?) then the heat on the rotor is only caused by the friction from braking. If thats the case I dont understand how they can be any hotter than the rim or a wheel on a rim brake bike as that has the same issue and being much larger, has a far greater chance for a rider's leg to touch a wheel as opposed a disk brake rotor.

Besides arent there covers people are making nowadays?

Because discs are smaller (hence why bigger discs dissipate heat better than smaller discs). 

However, the chance of a there being a crash onto hot brakes seems remote as they tend to happen on fast stretches, not at the bottom of a descent.

Probably not, but discs offer superior braking performance in every condition. No-brainer.

No, but most new bikes (hybrids) seem to have disc brakes, when I go shopping on the bike, most others have discs, mine having rim brakes looks ancient.

Aren't we losing the plot re disc brakes? Virtually all pedal cycles have disc brakes, the conventional around the rim brakes and the more recent trend towards inner wheel discs. The latter have a very small surface area which gets very hot and stays that way for longer as the heat does not desipate as quickly as a conventional rim disc brake. On a road bike the difference between the two is minimal with the conventional outer rim disc coming out in front because it is lighter and easier to maintain. The inner disc brake wins on multi terrain bikes when they may be subject to extremely wet/muddy conditions.

All bikes have disc brakes. There's rim discs and hub discs. Take your pick.

heard about homologation?  https://en.wikipedia.org/wiki/Homologation

In F1 btw only the fuel is homologated, but in cycling all the equipment that the pros use should be available for the public. Thats why you can buy the new felt track bike for 26k $.

Need? No. But it would be bloody fun wouldn't it! Same way i'd much rather ride around on my nice bike.

Maybe in a pro mass pile-up situation maybe they are potentially dangerous but it seems like every other new bike is sporting discs now and they're of no danger to the public/general Joe rider.

When you look at the injuries sustained in racing you could argue they need to be wearing knee and elbow protectors more than worrying about the odd burn. I can't imagine there'll be any rush towards that though.

Exactly. Knee + Elbow protectors = more weight / drag. I'm sure they'll be all over that.

Given the injuries the Pro Peleton stand to face in even a minor off, and seeing as a small burn seems to be the most he has to complain about, whingers like Sam Bailey need to MTFU.

Bewley?

A quick check of his record this year shows 7 X stage races including 2 GC's, many one day races including classics such as Paris Roubaix. You must be very well respected in the pro peloton to deem that he needs to 'MTFU' LOL.

All these people saying 'well there are worse injuries in cycling than being burnt so he shouldn't worry about being burned' - what a ridiculous statement. Nobody says cycling isn't already dangerous, these risks are accepted and mitigated where possible. Then his employer provides him with equipment that could cause another type of injury - he's got every right to flag it if he believes it to be dangerous. Wouldn't you, in your line of work?  

As for heat build up, most crashes on the flat are preceeded by heavy braking. No idea if that is sufficient to cause a burn, but might that be a factor?

All these people arguing with the pro's opinion to make an argument for disc brakes for the general public  - just let it go! what the pro's say has no relevance to your situation unless you are one yourself.

Has his employer provided him with this equipment?

Well presumably him and/ or his colleagues have been provided with them. If a load of pros have bought themselves disc-braked equipped bikes, had a race, crashed them, then moaned about not having 'safer' rim brakes, they've only got themselves to blame!!
