Protocol RCG-3
The RCG-3 is the successful result of Silca's mission to make the best gravel tire on the planet. Arriving at gravel tire development with a fresh perspective, they took the characteristics everyone loves about fast XC MTB tires and optimized them for modern gravel with ultra-fast road tire casing concepts. The RCG-3 delivers robust flat protection without sacrificing speed. It was engineered for harsh courses and unpredictable terrain like you find in Category 3 gravel events like Unbound, Big Sugar, and The Rift. The RCG-3 tread features tightly spaced, elongated center knobs that increase both in size and height as the pattern moves outwards to enhance buoyancy and contact patch during cornering. This clever shape keeps you rolling smoothly on the rubber rather than squirming on the casing. To maximize its unique structural layup, the RCG-3 is tuned for slightly higher baseline inflation. This optimized pressure dynamic prevents over-deflection, stabilizes the contact patch, and enhances pinch-flat protection without compromising traction or handling confidence. Accordingly, we added a new casing option to our tire pressure calculator to account for the differences needed for the race casing in Silca's tires. The result is a fast, supple, and resilient tire that allows riders to attack demanding courses knowing their speed won't be compromised by a flat.
- Pulsar Compound: A high performance rubber and silica race compound engineered to hold rolling efficiency, grip, and durability in balance rather than trading one away for another
- Race Casing: A race casing architecture developed around modern tire pressures, so the tire keeps its shape and its ride quality at the pressures wide rims actually run
- CarbonBead BeadLock: Carbon fiber bead technology that keeps the tire dimensionally stable across its whole life, so the width you measure at installation is the width you keep
- SealSkin: Enhanced puncture protection for terrain that asks more of the casing, adding durability where the ground is rough enough to make it part of being fast
- Tubeless Ready: Engineered for modern tubeless systems from the bead out, so sealant, valves, and lower pressures all work the way they were meant to
