CushCore - Single
Save your rim, save your tire. This option is for a single wheel, usually the rear.
CushCore® (Patent Pending) is an engineered foam insert that mounts inside a mountain bike tire. 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 – In other words an Inner-Tire Suspension System®.
