Despite the UCI’s disc brake trial continuing into a second season, there is still plenty of nervousness among the pros about the possible dangers of the new technology. And this nervousness was certainly shown in the response to this photo of Andre Cardoso’s close-call at the Tour de San Luis.

Posted on Twitter by fellow Cannondale rider Alex Howes, the photo shows a nasty injury on the inside of Cardoso’s thigh where he had got tangled up with a chainring in a crash. However despite there being no disc brakes involved in the crash, a number of pro riders picked up on the photo as highlighting the possible dangers of disc brakes during mass pile-ups.

Dimension Data‘s Nathan Haas retweeted the photo with the caption “why we probs don’t need disc brakes”, but received criticism from some users for trying to use an injury caused by a chainring to highlight the dangers of disc brakes.

Alex Dowsett was amongst those to leap to Haas’ defence, saying that “in a bunch pileup there’s bodies and bikes literally everywhere and in every position.”

However, as nasty as Andre Cardoso’s injuries look, this was far from the worst crash we’ve seen in recent days, with Adriano Malori in a medically-induced coma following a seperate crash at the Tour de San Luis, while six Giant-Alpecin riders were seriously injured in a crash at a training camp at the weekend.
