A recent statement by Cadex has shed light on a controversial incident involving a wheel failure during the Omloop het Nieuwsblad race. The incident, which left many questioning the safety of hookless rims, has been analyzed and the brand has provided an insightful explanation.
The Core Issue: A Wheel Failure and Its Causes
Amaury Capiot, a rider for Team Jayco-AlUla, experienced a catastrophic wheel-tyre system failure while riding on the cobblestones. Cadex, the brand behind the wheel, has stepped forward to clarify the cause, stating that it was not the design of the hookless rim that led to the failure.
The assessment, conducted with the team, revealed a more complex issue. It appears that the prolonged riding on cobblestones with a flat and damaged rear tyre caused the rim to crack, leading to a structural failure. This, in turn, displaced the spokes from the hub, causing the wheel to collapse and the tyre to become unseated.
But Here's Where It Gets Controversial...
Images from the incident show that Capiot was using a tyre liner, a common practice during cobbled races. Tyre liners are designed to offer protection to the rim in case of a deflation, providing a cushion to absorb impacts. However, in this case, the liner was not enough to prevent the rim from failing.
Cadex representatives have clarified that neither Giant nor Cadex recommend the use of tyre liners with their products. The team's decision to use a liner was outside the brand's guidelines, but it is important to note that the liner was not identified as a contributing factor to the failure.
The initial impact, according to Cadex, occurred at a speed of approximately 47-48kph. Capiot continued riding on the cobbles until the wheel ultimately gave way to the extreme forces. Interestingly, the brand mentions that even in this extreme scenario, the wheel remained stable enough to prevent a crash.
And This Is the Part Most People Miss...
While hookless rims have been a topic of debate, this incident highlights the importance of proper tyre maintenance and the potential risks of riding with a flat tyre, especially on challenging terrain like cobblestones.
