Engineered specifically for grueling high-speed gravel events like Gravel Worlds and SBT GRVL, the SILCA Protocol RCG-1 redefines what is possible when asphalt transitions seamlessly into dirt. This high-volume race tire bridges the gap between road-like efficiency and uncompromising off-road compliance, eliminating the sluggish drag traditionally associated with wide gravel tires.
As you push through loose corners and hammer across fast straightaways, the tire's advanced compound and supple casing work in harmony to absorb high-frequency chatter without sacrificing momentum. It delivers an unfair advantage that maximizes power transfer and cornering predictability, letting you attack every descent and sustain relentless speed from the starting gun to the finish line.
