Riddler Gravel Tire: Uncompromising Performance for Every Terrain
Engineered for gravel enthusiasts and cross-country racers alike, the Riddler Tire delivers relentless grip and efficiency across mixed surfaces. Its asymmetric tread design combines dual-density rubber compounds—a high-density center rib minimizes rolling resistance at 25-35 PSI for sustained speed on fire roads or pavement transitions, while reinforced shoulder knobs (6mm height) bite into loose gravel or muddy trails during aggressive cornering maneuvers.
Key Innovations:
– Tubeless-ready folding bead (120 TPI) reduces pinch flats by 40% vs standard clinchers
– Dual-compound tread extends lifespan by 30% compared to single-compound competitors
– Sidewall protection layer resists cuts from sharp debris encountered on backcountry routes
Ideal for:
✔️ Competitive cross-country events (XC2/3/4 categories)
✔️ Endurance gravel marathons (200+ mile races)
✔️ Mixed-surface training rides (road-to-gravel transitions)
