Common pneumatic tire systems, whether tubed or tubeless, have come a long way since they were invented about 130 years ago. However, they act like air springs, bouncing and deflecting off obstacles because they provide no damping of compression or rebound forces.
CushCore, hailing from Bend, OR has engineered a foam insert that mounts inside a mountain bike tire, providing a solution to this problem. It divides the inside of the tire in half with air directly underneath the tread and the CushCore insert next to the rim. They work together as a spring and damper, making for faster, smoother rides on rough terrain with improved traction, stability and cornering control, while adding extra tire and wheel protection at only 250 g per wheel. To sum it up, CushCore’s innovative solution is an Inner-Tire Suspension System.
