Rampart Gravel Bike Tire

Engineered for cyclists navigating mixed surfaces—from crumbling backroads to technical gravel trails—the Rampart delivers adaptive performance without compromising speed or durability.

Key Innovations
✓ Tubeless-Ready Construction: Eliminates pinch flats and enables 15-20% lower pressure (55-80 PSI) for superior shock absorption on uneven terrain
✓ Asymmetric Tread Design: Center 4mm tread strip minimizes rolling resistance on paved sections; dual-density side lugs with triple-wave siping bite into loose gravel and mud
✓ Lightweight Durability: 60 TPI nylon casing withstands punctures while maintaining responsive handling (622mm bead diameter compatible with road/gravel frames)

Ideal For
▸ Adventure cyclists tackling mixed pavement/gravel routes
▸ Endurance riders seeking vibration damping over 100+km rides
▸ Urban commuters navigating pothole-ridden streets

Built with a folding Kevlar bead (saves 120g vs wire beads) and optimized for 700x28c tubeless setups, this tire adapts to city streets or mountain passes while maintaining predictable cornering at speeds up to 40km/h. The proprietary tread compound balances low rolling resistance (8% faster than standard gravel tires on asphalt) with exceptional abrasasion resistance in rocky environments.
