Pro Tire Insert 29", Single With Valve

- 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\n- Absorbs impacts, reduces vibration and adds lateral stability to the tire\n- Third party testing has revealed that, compared to a standard tubeless setup, Cush Core provides a 12% smoother ride, 35% more sidewall stability, 16% less suspension travel consumption, 3% less rolling resistance, and 50% less impact force transferred to the rim\n- This system is designed to be used with tubeless ready or tubeless converted mountain bike rims and tires, as well as standard tubeless sealant\n- Doesn't absorb sealant like other tire inserts on the market\n- Includes special tubeless air valves that allow air to move through the valve without becoming obstructed by the insert\n- Amazon.com sales are strictly prohibited by the Manufacturer
