CushCore is an engineered foam insert to be 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.

  • Fits tire widths 2.1 - 2.6 and rims with internal width 22 - 35mm
  • The system is designed to be used with tubeless-ready or tubeless converted rims and tires, and is compatible with tubeless tire sealants
