Protocol RCG 3 Gravel Bike Tyre

The RCG-3 is the successful result of our mission to make the best gravel tire on the planet. Arriving at gravel tire development with a fresh perspective, we 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. Built around our supple Pulsar casing, the RCG-3 integrates an under-tread puncture breaker selected through many rounds of testing for its superior impact resistance. Unlike conventional protective tires that feel heavy and sluggish due to high internal friction, the RCG-3 architecture minimizes hysteretic losses to protect against flats while maintaining optimal rolling efficiency and traction. 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 our 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.
