The Silca Protocol RCG-1 Fast Gravel Tubeless Folding Tyre is engineered for maximum speed on hardpack, smooth dirt, and tarmac transitions. Designed around modern wide-rim standards, it pairs the straight-line rolling efficiency of a slick with cornering control via elevated shoulder knobs, delivering race-day performance without sacrificing weight or compliance.
A NEW APPROACH
Protocol was developed to build the race tyres SILCA wanted to ride. Tyres designed around today's racing conditions. Tyres available in the widths modern riders actually want. Tyres that balance rolling efficiency, grip, ride quality, puncture resistance, and modern tyre system compatibility instead of chasing a single performance metric. Because the fastest tyre isn't always the same tyre.
WHY PROTOCOL?
For years, SILCA has developed products that help riders better understand and optimise the complete tyre system. Every product contributed to a better understanding of how modern tyres perform and how riders can optimise them for speed, efficiency, confidence, and control. That journey led to:
Each product answered part of the equation. Eventually, there was one component left. The tyre. The fastest tyre is the one optimised for today's ride terrain and condition priorities.
THE COMPLETE PERFORMANCE EQUATION
Designing a modern race tyre isn't about maximising a single performance characteristic. Every improvement has the potential to influence something else. More puncture protection can increase weight. More grip can affect rolling efficiency. Lower tyre pressures can improve comfort and traction while changing handling characteristics. The goal isn't to maximise one attribute. The goal is to optimise the complete performance equation. Every engineering decision in Protocol exists because it contributes something meaningful to the complete performance equation.
PERFORMANCE OUTCOMES
Every Protocol tyre was developed to balance the performance outcomes that matter most on race day. No Protocol tyre is designed to maximise every performance outcome. Every Protocol tyre is built around the same performance equation. The difference is how each model balances it for different racing conditions.
ENGINEERING PHILOSOPHY
Every Protocol tyre shares the same engineering philosophy. Every engineering decision earned its place by contributing something meaningful to the complete performance equation. The difference isn't the philosophy. The difference is how each model balances the complete performance equation for different racing conditions.
ENGINEERED TOGETHER
Protocol wasn't developed in isolation. It was engineered alongside the SILCA Tyre Pressure Calculator, Ultimate Sealant, Tubeless Valves, Rim Tape, and TPU Tubes because every component contributes to the complete performance equation. The setup recommendations help riders get the performance Protocol was designed to deliver.
PROTOCOL GRAVEL
Modern gravel racing demands different tyre characteristics for different racing conditions. Rather than asking one tyre to excel everywhere, Protocol offers three purpose-built directional tread patterns. Every Protocol gravel tyre is built around the same engineering philosophy. The difference is how each model balances the complete performance equation for different racing conditions.
