Silca Protocol RCG-3 Folding Gravel Tyres With Silca Ultimate v2 500ml Tubeless Sealant - Pair
When lining up in Emporia, KS or Bentonville, AR finding the fastest tire that won't flat is key. This is the choice for those types of courses. More grip, more puncture protection, and all the speed.
The RCG-3 is the successful result of Silca's mission to make the best gravel tyre on the planet. Arriving at gravel tyre development with a fresh perspective, Silca took the characteristics everyone loves about fast XC MTB tyres and optimized them for modern gravel with ultra-fast road tyre 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, Silca added a new casing option to there tyre pressure calculator to account for the differences needed for the race casing in Silca tyres. 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.
RCG-3 Architecture
Tightly spaced, elongated center knobs increase in both size and height as the pattern moves outward, building buoyancy and contact patch through the corner. That shape keeps you rolling smoothly on the rubber rather than squirming on the casing.
Performance Data
The RCG-3 returned 24.7 kg of puncture resistance in controlled lab testing, well ahead of the Continental Dubnital at 22.3 and the Schwalbe Thunder Burt at 19.9. It rolls faster than the Dubnital at 28.2 watts and undercuts both on weight, so the added protection arrives without the penalty that usually comes with it.
Ideal Conditions
Harsh courses and unpredictable terrain, the kind you find in Category 3 gravel events like Unbound, Big Sugar, and The Rift. When you do not know exactly what the day holds, this is the tire to start with.
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.

Silca Ultimate v2 Tubeless Sealant - 500ml
Injectable through your valve, seals a 6mm+ puncture, and lasts up to 6 months. The perfect sealant for those looking for the ultimate sealing power, longevity, and ease of use.
The original sealant formulation, released 2.5 years ago, was designed primarily for effective puncture sealing by maximizing the surface area of the liquid latex for enhanced performance. Pro racers valued its convenience, as they frequently changed tires based on race conditions and could easily pour in fresh sealant without needing to inject it through the valve. However, we heard two main concerns from more casual cyclists—it dried out quickly when not in use, and its composition of the longer strand carbon fiber made injection difficult and problematic, leading to a potentially messy installation if not handled carefully.
Lastly, the old Natural Latex formula needed a two-step process to stay liquid longer. That has been eliminated with our new blend of natural and synthetic latex. SILCA Ultimate Sealant Is a one-step process lasting +6 months and still, above all else, sealing punctures on race day.
