What sets CushCore inserts apart from other tire inserts on the market is that they're not just for flat-tire protection. The engineered foam insert acts as a damper to reduce vibration at the bar, diminishes tire deflection off obstacles, and stabilizes the tire against roll and squirm in the corners and at high speed - it even provides run-flat capabilities. Think of it as suspension for your tires optimized to give you a faster, smoother ride. CushCore is designed for tubeless tire systems.

CushCore is designed as a system to be used in both the Front and Rear Wheels — each kit includes 2 inserts and 2 air valves

CushCore PRO fits tire widths 2.1″ to 2.6″ and inner rim widths 22mm to 35mm.
