The Equipo Kern Pharma staff has showed that Marc Brustenga’s freak crash on level 2 of Étoile de Bessèges resulted from an previous incident during which the rim was once broken.
Because the Spaniard started his dash within the ultimate few hundred metres of the race into Marguerittes on Thursday, his rear tyre blew and a cloud of tyre sealant exploded out, failing to seal the obvious puncture.
In consequence, Brustenga veered left and slid out, crashing into the boundaries. Thankfully, he have shyed away from critical damage, however out of precaution he opted to not get started level 3, and regardless of the peloton charging at the back of him, no one else was once suffering from the crash.
It was once unclear on the time what brought about the puncture, nor certainly whether or not the tyre got here off the rim within the preliminary blowout or within the next have an effect on with the boundaries.
“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.”
The wheels in query are the 50 Extremely Disc Tubeless wheels, equipped through Cadex Biking, which is the element subsidiary of Kern Pharma’s motorcycle sponsor Massive motorcycles

The wheels are built the use of a proprietary Cadex hub, deep-bladed aero spokes, and a 50mm deep carbon fibre rim with hookless bead.
Hookless generation was once on the centre of a security debate within the spring of 2024 when Thomas De Gendt’s tyre gave the impression to blow in a in a similar way surprising model on the UAE Excursion. He was once the use of a Vittoria tyre and a hookless Zipp rim on the time, and the incident precipitated an investigation through the UCI, regardless of later being confirmed that the rim was once broken through the Belgian hitting a rock within the street.
Brustenga’s rim suffered structural harm within the incident too, with a vital crack to the rim sidewall, as proven within the symbol underneath.
