CushCore is an engineered foam insert mounted inside a tire designed to absorb impacts reduce vibration and increase lateral stability. These characteristics translate to a more controlled comfortable and faster ride. The system is designed to be used with tubeless-ready or tubeless converted rims and tires and is compatible with tubeless tires. The insert divides the inner volume of the tire in half maintaining air underneath the tread and the foam insert next to the rim. Valve stem included.
