SMARTplus Compound

“The GRAVINE comes with the gravel-specific tread compound, made of special higher durometer, natural SMARTplus rubber. While providing reduced wear and enhanced durability, the SMARTplus rubber compound still retains its natural properties and offers improved shock-absorption, better grip and control, and reduced rolling resistance.”

Corazza Armor Gold

“Exclusive feature of the XP tire range is the Corazza Armor Gold, which increases the tire’s puncture protection and robustness further, by including an additional Bead-to-Bead layer of tightly woven material. The additional layer reinforces the entire tire and makes the GRAVINE XP a great tire for more endurance riding or simply a more dependable tire on more rugged terrains, in multiple and adverse conditions.”

Chafer Aramid Bead Protection Strip

“The GRAVINE includes a bead protection outer strip that enhances tire longevity against the rim, by reducing the effects of chafing or rubbing against the rim’s bead hooks. Additionally, the contrasting black, precise chafer line that shows around the rim, acts as a visual confirmation, that the tire bead has been properly seated all-around the rim”
