The edge of damage is the cause Freak tire blowout This caused the crash of Marc Brussenga in the second phase of the Etoile de Bessèges, according to rider team Kern Pharma.
Brustenga lost control of her bike, turned sharply on the road and hit a safety barrier during the closure moment of the stage on Thursday.
The video shows that he has not been in contact with other riders, but is the victim of the freak rear tire blowout. He finished the stage on foot, crossed the bike over the line, and the rear tires fell completely off the rim.
Since his Kern Pharma team used hookless rims provided by Brand Cadex, there are questions about the unfortunately caused by the problem between the rim and the tubeless tire.
A team spokesperson told Bicycle rides every week On Friday, the incident has now been “completely investigated”.
“Hundreds of meters before the piercing, Brusten entered a roundabout and hit a hole, which slightly damaged the edge of Cadex due to speed,” Kern Pharma said.
“But he felt he could keep riding, and he did. The tire could no longer support its rims because of the last crash.

The incident is reminiscent of an incident involving Thomas de Gendt. The Belgians also rode hookless rims, suffered a blowout from their tires and crashed. The reason was later attributed to early damaged wheels on the stage.
De Gendt said at the time: “Zipp had a steering wheel to investigate and their investigation said it was because of rocks or something on the road.” “After the stage, I saw the damage, and it was not only The damage to hit the road and it does get damaged by hitting something.”
Nevertheless, the De Gendt incident stimulated UCI’s investigation into hookless rims using tubeless tires. The governing body continues to remind the team to comply with compliance regulations set by the International Organization for Standardization (ISO).
“These standards provide a frame for compatibility between tires and rim widths on bikes,” UCI said.
“UCI points out that the specifications defined in these ISO standards are not always respected and do not rule out the possibility that this may be a contributor to certain events encountered.”
