Tubeless tyre blowout causes heavy crash in sprint finish at Étoile de Bessèges
Rear tyre was ejected from the rim in the impact after Spaniard tried to ride on after hitting pothole

In the sprint finish on stage 2 of the Étoile de Bessèges, Marc Brustenga (Equipo Kern Pharma) was sitting in 10th wheel with 100m to go when he inexplicably veered left, lost control of his bike, and crashed into the barriers.
At first, it seemed as though the Spaniard had crossed wheels with Sam Bennett (Decathlon AG2R La Mondiale) as he tried to pass but the overhead shots told a different story.
In the video below from Eurosport, at 43 seconds, a small white cloud emanates from Brustenga's rear wheel just as he leans left to pass Bennett.

The reason for this is that his tubeless tyre had punctured, with the white tubeless sealant inside exploding out in an instant, failing to seal whatever damage had been done to the tyre.
Images captured of the sprint finish show Brustenga in the background, midway through his incident with the bike bouncing through the air, his rear tyre ejected from the rim and instead entangled around the frame of the bike.
Luckily, despite the swirling peloton powering toward the finish line behind him, he was the only rider to go down, and importantly, a subsequent tweet from his Equipo Kern Pharma team's X account has confirmed the Catalan rider came away with "many abrasions and injuries" but otherwise "fine and able to cross the finish line."
The cause for the blowout has since been confirmed as delayed failure following an earlier incident in which Brustenga hit a hole on a roundabout.

A statement from the team to Cyclingnews explained that "a few hundred meters before the puncture, Brustenga entered a roundabout and hit a hole, which slightly damaged the CADEX rim due to the speed. However, he felt that he could continue riding, and he did."
It is unclear from the footage of the incident as to whether the tyre came off the rim immediately in the blowout, or whether it was shed in the aftermath as a result of hitting the barriers, as was the case in Annemiek van Vleuten's not-dissimilar crash at the 2022 World Championships.
