Gravel/CX Tyre InsertsCushCore is an engineered foam insert that mounts inside a mountain bike tyre. It divides the inner volume of the tyre 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 tyre against roll and squirm. Think of it as suspension
