CushCore XC Tire Inserts Set 29" Pair Includes 2 Tubeless Valves delta e trikes and 110-Series headsetsHow Cushcore Works CushCore is based on a new concept: Tire Suspension. Any suspension system has a spring and a damper, and with CushCore, pressurized air in the tire is the spring and the CushCore tire insert is the damper. Also like traditional suspension, a constant damping force wouldnt work. It has to be dynamic. Suspension should be supple on small bumps but firm on big hits. CushCore responds differently depending on the tire loading scenario.
