On tubeless wheels, punctures happen when the tire is pinched between an external object and the edge of the rim. Increasing the width of the rim profile in these points greatly reduces the likelihood of these punctures.
We use a wider bead with a larger radius to spread the force of the impact and reduce the risk of a puncture. The beauty of this technology is that the wider bead is also more resistant to damage in the event of a puncture or extreme impact
Using wider beads at the rear offers two advantages: firstly, it helps to increase stiffness, improving acceleration, and secondly, it offers additional protection at the rear, where most punctures occur.
