Cush Core XC Tire Insert 27.5" (650b) Set with Valves

From N+1 Bikes

A smaller, lighter version to fit XC tire sizes and riding style- 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- Absorbs impacts, reduces vibration and adds lateral stability to the tire- This system is designed to be used with tubeless ready or tubeless converted mountain bike rims and tires, as well as standard tubeless sealant- Doesn't absorb sealant like other tire inserts on the market- Includes special tubeless air valves that allow air to move through the valve without becoming obstructed by the insert
