another example of disc brake "cuts"
a friend recently got into a bit of a tangle while in a fast group ride. in the melee one guy ran into the back of another. this image shows rear tire damage when the rear guy contacted from behind. the rotors are shimano ultegra SM-RT800, not sure if they have the safety/rounded edge.
reinforces the idea that disc rotors are capable of cause injury comparable to chainrings. |

There's a moving chain and rotating gear teeth on the other side of that hub.

So, let's put more crap that can hurt you?

Mountain bikes have had them for decades. And it was a tire that got hurt because someone rode into the back of another bike. How does that relate to a person? There have been pro tour riders that were cut by discs in crashes, but more wounds are caused by pavement, fences, barriers, and the overall effects of gravity when a rider goes off course.

Not sold.
There's a disconnect between the admittedly non scientific tests we see all around the internet and these reports from the most unreliable of witnesses: the people who have experienced crashes firsthand. I have a hard time thinking we haven't seen mention of any prominent injuries due to rotors in, say, downhill where crashes are, it goes without saying, epic. I'm skeptical of discs on the road generally, but I'm not sure leg safety is making those list of reasons why quite yet for me. |

If you ride into the back of another bike in a paceline, you aren't hitting the other guy's rotor. You're hitting the ground because you touched wheels. It's physics, the other guy isn't going down, you are and the other guy is rolling away. And the riders behind you with disc brakes somehow have to hit you with their brake rotor which is a smaller diameter than the wheel around it.

Not sure why this is even an argument. Discs on bicycles are here to stay, for good or ill, with the 'warts' that come with them, like any bike 'gadget'...

I'm actually of the same opinion. I suppose its possible that discs could present some additional safety hazards - but the situations in which those hazards come into play already present so many other dangers, that any additional dangers posed by disc brakes are marginal. |
