THE FASTEST SOLUTION EVER FOR MIXED TERRAIN. Made with Panaracer's ZSG GRAVEL compound and featuring a unique tread pattern, the GRAVELKING ZX has been designed to ensure speed and stability without having to change tires between rides. Panaracer has expanded its highly popular GRAVELKING line with the introduction of the GRAVELKING ZX, a brand new gravel tire designed for cyclists seeking speed on gravel routes with mixed surfaces. Since modern gravel riding is rarely limited to a single type of surface, transitioning from paved roads to loose terrain descents and rocky climbs, there is a need for a tire that balances speed, grip, and durability across different surfaces. The GRAVELKING ZX meets this need, offering low rolling resistance along with the grip and durability required when conditions become more challenging. A three-zone tread for speed and control. At the heart of the GRAVELKING ZX is a three-zone tread pattern, designed to maximize speed while preserving safe handling on varied terrain. This is made possible by a smooth center tread that minimizes rolling resistance and maintains momentum on asphalt and compact gravel.  The inner edge of the ZX uses a transition tread that engages during braking and cornering, maintaining grip and ensuring a predictable feel.  On the outer edge, aggressive side knobs provide the traction needed for cornering on loose gravel, technical descents, and rougher surfaces, giving cyclists the control required when the terrain becomes more challenging. Together, these three zones allow the ZX to maintain speed where it matters most, while offering the feel and confidence that gravel cyclists expect.
