CushCore Tire Inserts (Set of 2), with Tubeless Air Valves, 27.5"

What sets CushCore apart is that it's not just for flat protection. The engineered foam insert absorbs shock, stops deflection off obstacles, reduces vibration, and stabilizes the tire against roll and squirm - 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-ready or tubeless converted mountain bike rims and tires. CushCore fits tire widths from 2.1" to 2.6", and fits rims with internal widths from 22 to 35mm.
