Utilizing dual-density design with Rimpact Original Foam, it provides maximum protection with minimal weight. This innovative insert enhances traction, support, and stability, allowing racers to focus on performance. Ideal for both seasoned racers and beginners, it helps reduce the risk of flats and crashes, enabling lower tire pressures for better traction.

| Width / Rim: | 17mm - 25mm |
| Weight: | 55g per insert |
Compatibility
Specifically designed for UCI spec CX tires (33c) but compatible with any rim with an inner diameter of 17mm - 25mm and tire widths 33c to 45c. (Keep in mind that the difficulty of fitting increases dramatically the narrower your rims are).
Hookless Rims are compatible, but if you run close to min or max pressures recommended by the rim and tire manufacturer, the risk of blowouts is increased. This is not due to the Rimpact but the nature of the hookless design.
Use about 25% more sealant than recommended on the bottle to ensure the extra surface area of the insert is well coated. Rimpact inserts are closed cell and cannot absorb liquid. Some sealant will cling to the outside of the insert requiring a slightly higher dosage.
Disclaimer: Do not run air pressures outside the tire manufacturer's recommendations. Failure to do so may result in injury or the premature failure of the bicycle. Rimpact does not accept any responsibility for misuse of the Rimpact insert or improper installation. Rimpact Inserts are designed to work WITH Rimpact Insert Compatible Valves.
