CushCore is based on a new concept: Tire Suspension. Any suspension system has a spring and a damper, and with CushCore, pressurized air in the tire is the spring and CushCore is the damper.

Also like traditional suspension, a constant damping force wouldn’t work. It has to be dynamic. Suspension should be supple on small bumps but firm on big hits. 

CushCore responds differently depending on the tire loading scenario. The more the tire flexes, the more damping it provides.  We break it down into small, medium, and large tire deflections.

Three Stages of Tire Suspension

Small tire deflections

Under normal load or “just rolling along”

  • Little or no damping
  • Lively feel
  • Less rolling resistance than tubeless

medium tire deflections

Bumps and corners that flex the tire sidewalls

  • Moderate damping
  • Interacts with tire sidewalls
  • Supports tire sidewalls (stable/less tire roll)
  • Controlled rebound (less bounce and deflection)
  • Less vibration


large tire deflections

Impacts that fully collapse the tire

  • High level of damping
  • Dissipates the impact energy
  • Reduces bump force experienced by the rider
  • Damps rebound force, helping tire to remain in contact with the ground
  • Protects the rim and helps prevent flats
