Built for speed on fast gravel courses, the SILCA Protocol RCG-1 combines the rolling efficiency of a hardpack slick with the high-volume compliance of an XC race tyre. Available in 45mm, 50mm and 55mm widths, it's designed around modern gravel tyre sizes, wide rims and lower running pressures.
The low, ramped directional centre tread is designed to minimise rolling resistance while providing a defined braking surface when slowing down. Lean into a loose, high-speed corner and the elevated, elongated side knobs increase contact with the ground for additional grip and stability. The result is a tread designed to roll quickly in a straight line while maintaining confidence when cornering.
SILCA's Pulsar rubber compound balances rolling efficiency, grip and durability, while the 120 TPI Race Casing is designed around modern gravel tyre pressures. Lightweight GhostShield puncture protection adds security without compromising the tyre's focus on speed, while CarbonBead BeadLock technology provides dimensional stability throughout the tyre's service life.
