Ideally a tire would act more like a suspension system with both a spring and a damper, where the spring supports the load and the damper dissipates the energy.
CushCore delivers that technology to tires for the first time. It is an engineered foam insert that mounts inside a mountain bike tire and divides the inner volume of the tire in half, with air underneath the tread patch and the CushCore insert next to the rim. They work together as a spring and damper – In other words, an Inner-Tire Suspension System.
Domestic and international patents are pending.
the problem with pneumatic tires
Pneumatic tires were a huge leap forward when they were invented nearly 130 years ago. Meanwhile, mountain bike technology has become incredibly sophisticated — we have full suspension, disc brakes, and carbon fiber — but we are still riding on pneumatic tires.
The problem is that pneumatic tires behave like air springs. They bounce and deflect off obstacles because they provide no damping of compression or rebound forces. This increases rolling resistance and makes the bike harder to control.
