Silca Protocol RCG-3 Gravel Tyre

Years of studying tyre pressure, rolling resistance, aerodynamics, vibration losses, rim width, sealant, valves, rim tape, and TPU tubes taught us that a modern race tyre is more than tread and rubber. It’s part of a complete tyre system where every engineering decision affects performance. We weren’t looking to make another tyre. We were looking to build the tyres we wanted to ride. Tyres designed around the conditions we race, the widths we believe modern riders need, and the performance characteristics we value most. Protocol RCG-3 Directional tread balanced all-around race tyre for mixed terrain & changing conditions and an emphasis on puncture protection. Ideal for: Modern gravel race platforms Mixed terrain race builds Performance gravel geometry Protocol RCG-3 Technologies Pulsar Compound Hi-performance rubber/silica race compound engineered to balance rolling efficiency, grip, and durability. Race Casing High-performance casing architecutre developed around modern tyre pressures. CarbonBead BeadLock Carbon fibre bead technology that maintains dimensional stability throughout the life of the tyre. SealSkin Enhanced puncture protection for conditions where additional durability becomes part of the complete performance equation.
