Cadex Defends Hookless Rims in Amaury Capiot's Wheel Failure
Cadex has issued a statement addressing the recent incident involving Team Jayco-AlUla rider Amaury Capiot's wheel-tyre system failure at Omloop het Nieuwsblad. The brand clarifies that the tire separation was not caused by the hookless rim design, but rather by prolonged riding over cobblestones with a flat and damaged rear Cadex Aero Cotton tyre.
The Rim's Structural Failure
Cadex's assessment revealed that the rim cracked due to prolonged riding over cobblestones with a flat and damaged rear tyre. This structural rim failure caused the spokes to displace from the hub, leading to the wheel's 'collapse' and the complete unseating of the tyre from the rim.
Tyre Liner's Role
Images from the incident show a tyre liner in place around the Cadex Ultra 50 rim, a common addition to tubeless tyre setups for improved 'run-flat' riding. However, Cadex clarifies that the team was operating outside the recommended guidelines, as neither Giant nor Cadex endorse the use of tyre liners with their products. Despite this, the liner did not contribute to the failure.
Initial Impact and Riding Conditions
Cadex states that the initial impact occurred at approximately 47-48kph, and Capiot continued riding on cobbled sections until the wheel collapsed. The brand emphasizes that the wheel remained stable enough to prevent a crash, despite the extreme forces involved.
Controversy and Counterpoints
This incident sparks discussions about the use of tyre liners and the guidelines set by manufacturers. While Cadex clarifies that the failure was not due to the hookless rim design, the team's deviation from recommended practices raises questions about the optimal setup for such events. This controversy invites further debate on the best practices for wheel and tyre maintenance in professional cycling.
