Before disc brakes became UCI legal there was a lot of people arguing that they were more dangerous than standard v brakes in bunch races. Often it was highlighted that a very hot spinning metal disc could slice through skin or tissue very easily.

Discs have now been in pro and local races for quite a while - I was wondering if there were any examples of this actually happening?

    The proper question would probably be "Are disk brakes considerably less safe than rim brakes". Or what is the goal of the question, actually?

  • How often have handle bar ends, or rim brakes, or shift levers or derailleurs or ... caused injuries in a bike race? Are the number of disk brake related injuries in line with other types of injuries or are they significantly higher or lower? Otherwise, just asking about a single data point isn't very instructive.

Reports are becoming more common: https://www.cyclingweekly.com/news/cyclocross-rider-hospitalised-after-disc-brake-causes-wound-484217

Van Anrooij's team, Telenet-Baloise Lions, put out a statement on Twitter saying: "Shirin Van Anrooij's forearm was injured by a piece of a disc brake in the crash following the start of the race. She will undergo surgery this evening. At this moment, it looks like no muscles or tendons are heavily damaged,"
Team manager, Sven Nys, said in an interview with Wielerflits he has never seen an injury like it, but Van Anrooij was conscious as she headed to hospital.
"It is an open wound and there is also a fracture," he said.
