Silca Protocol RCG-4 700c Gravel Tire

Description

Performance Tires for Modern Race Conditions

The Silca Protocol RCG-4 Gravel Tire features a directional tread made to shed mud and have maximum traction and control for rough, loose, and technical terrain. The toughest, most capable member of the new Protocol gravel lineup, this tire is optimized for "Category 4" gravel riding, aligning with recommendations from Silca's own tire pressure calculator.

Modern gravel racing demands different tire characteristics for different racing conditions. Rather than asking one tire to excel everywhere, Protocol offers three purpose-built directional tread patterns. Every Protocol gravel tire is built around the same engineering philosophy. The difference is how each model balances the complete performance equation for different racing conditions. The RCG-3 is ideal for technical gravel builds, high-volume race setups, and progressive gravel platforms.

The Complete Performance Equation

Designing a modern race tire isn't about maximizing 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 tire pressures can improve comfort and traction while changing handling characteristics.

The goal isn't to maximize one attribute. The goal is to optimize the complete performance equation. Every engineering decision in Protocol exists because it contributes something meaningful to the complete performance equation.

For years, Silca has developed products that help riders better understand and optimize the complete tire system. Every product contributed to a better understanding of how modern tires perform and how riders can optimize them for speed, efficiency, confidence, and control. That journey led to:

• The Silca Tire Pressure Calculator
• Ultimate Tubeless Sealant
• Ultimate Tubeless Rim Tape
• Ultimate Tubeless Valves
• Ultimate TPU Tubes

Each product answered part of the equation. Eventually, there was one component left: The tire. That's the Protocol.

Features:

• Pulsar Compound: Hi-performance rubber/silica race compound engineered to balance rolling efficiency, grip, and durability.
• Race Casing: High-performance casing architecture developed around modern tire pressures.
• CarbonBead BeadLock: Carbon fiber bead technology that maintains dimensional stability throughout the life of the tire.
• SealSkin: Enhanced puncture protection for conditions where additional durability becomes part of the complete performance equation.
