CushCore Set / 2 Inserts + 2 Valves


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.

The purpose of Cushcore is to improve the ride quality of your bike.  It is not just for flat protection.  CushCore absorbs shock, stops deflection off obstacles, reduces vibration, and stabilizes the tire against roll and squirm.  Think of it as suspension for your tires designed to give you a faster, smoother ride.

This system is designed to be used with tubeless-ready or tubeless converted mountain bike rims and tires.  CushCore is compatible with tubeless tire sealants.

CushCore is sold as a set, and is designed for use in both front and rear wheels.  Specially designed tubeless air valves are included with each set.  The air valve allows air to move through the valve without becoming obstructed by the insert.
