    • CushCore Gravel-CX Tubeless Tyre Insert Set

  • CushCore Gravel-CX Tubeless Tyre Insert Set

    This insert set is specifically engineered for the demands of gravel bike riding and cyclocross (CX) racing and includes everything you need to transform how your bike's tyres respond to bumps, vibrations and shocks from the terrain. Benefitting from a revolutionary concept that improves suspension performance and reduces impact force, it's a great choice of upgrade for increased confidence on your back road and countryside adventures. With increased sidewall stability, CushCore has developed this model to allow for harder cornering, making it ideal for cyclocross while also eliminating tyre squirm and burping, even at low tyre pressure. Another highlight is it delivers reduced rolling resistance and a smoother overall rolling experience, meaning you can ride faster with more control, more momentum, and less fatigue.

    How It Works

    Not all tyre inserts are created the same. CushCore is no ordinary tyre insert and is based on a new concept, tyre suspension. Any suspension system has a spring and a damper, and with CushCore, pressurised air in the tyre is the spring and the CushCore tyre insert is the damper. Like traditional suspension, a constant damping force wouldn't work. It has to be dynamic. Suspension should be supple on small bumps but firm on the big hits. CushCore responds differently depending on the tyre load and scenario. The more the tyre flexes, the more damping it provides.

    Go Bigger

    CushCore improves suspension performance by 16% and reduces impact force from big hits by 50%. Send it with total confidence.

    Corner Harder

    35% more sidewall stability eliminates tyre squirm and burping, even at low tyre pressure. Rail corners with total confidence.

    Ride Faster

    CushCore provides a 12% smoother ride and 3% reduced rolling resistance. Ride with more control, more momentum, and less fatigue. It's like taking fewer punches in a fight.
