Rear spare wheel
Like any wheel with an inner tube and a tire, and despite its excellent tires and the anti-puncture product injected before delivery, the Escargoline can puncture.
Most of the time you can repair it with a puncture spray, or repair it on site with patches.
It could happen that a violent impact on a rock deforms the wheel to the point of rendering it unusable.
One solution is to carry a spare wheel with you.
