CushCore is an engineered foam insert that mounts inside a mountain bike tire. It divides the inner volume of the tire in half, with air underneath the tread and the CushCore insert next to the rim.

Test results show CushCore provides up to a 50% reduction in vertical impact force, a 77% reduction in lateral vibrations, and a 58% reduction in longitudinal vibrations. CushCore also adds lateral stability by exerting a constant outward pressure against the tire sidewalls. This eliminates excessive tire roll in corners, even at tire pressures as low as 10 psi.
