Full details

The CushCore Gravel/CX Tyre Insert Set is designed for gravel and cyclocross cyclists looking to maximize tire performance and wheel protection.

FAQs

Will this fit all gravel rims?

It is compatible with rims having an inner width between 19mm and 26mm.

Can I use these with tubes?

No, CushCore is designed specifically for a tubeless setup.

Do I need special tire sealant?

No, standard tubeless-compatible sealant works fine, though you may need a slightly larger quantity as the insert occupies space in the tire.

Does it increase rolling resistance?

Quite the opposite; it is designed to offer a 3% reduction in rolling resistance by improving tire deformation characteristics.

Is the insert reusable?

Yes, the insert is durable and can be moved to new rims or tires if you change your setup.

Troubleshooting

Difficulty seating the final tire bead

Ensure the beads of the tire are pushed deep into the center channel of the rim all the way around before trying to seat the final section.

Air not flowing through the valve

Ensure the CushCore valve is not pressed directly against the insert; the valve design allows air to pass around the insert, but ensure it is not blocked by improper seating.

Pros and Cons

Pros

  • Significantly reduces the risk of pinch flats and rim damage
  • Improves cornering confidence through increased sidewall support
  • Noticeable reduction in trail vibration and rider fatigue
  • Includes all necessary components for a complete tubeless upgrade

Cons

  • Installation can be physically demanding and time-consuming
  • Adds approximately 120g per wheel to the rotating mass
  • Requires specific rim and tire width compatibility

Setup, Compatibility & Care

To ensure optimal performance, confirm your rim's inner width is between 19mm and 26mm and your tires measure between 33mm and 46mm. Installation involves mounting the insert inside the tire before seating the final bead; using tire levers and plenty of sealant is recommended to make the process easier. The kit includes 44mm Presta valves specifically designed to allow airflow around the insert. To maintain the system, check your sealant levels periodically, as the insert may absorb a small amount over time. Ensure the rim stickers are applied to maintain a proper seal and identification.
