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 the CushCore tire insert 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.
What really happens during a bump impact? Check out the slow-motion analysis.
THREE STAGES OF TIRE SUSPENSION
SMALL TIRE DEFLECTIONS
Under normal load or “just rolling along”
Little or no damping
Less rolling resistance than tubeless
MEDIUM TIRE DEFLECTIONS
Bumps and corners that flex the tire sidewalls
Interacts with tire sidewalls
Supports tire sidewalls (stable/less tire roll)
Controlled rebound (less bounce and deflection)
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
The graph shows front suspension data with and without CushCore. The bar height is the total number of compression strokes during a ride. The bars are grouped into suspension travel ranges, from 10-20mm, from 20-35mm, and so on. With CushCore, there are fewer compression strokes in each group. CushCore turns big bumps into medium bumps, and medium bumps into smalls bumps.
