Silca Protocol RCG-3 Gravel Tyre 700C

BUILT FOR FAST, DEMANDING GRAVEL WHERE SPEED ALONE ISN'T ENOUGH, THE SILCA PROTOCOL RCG-3 COMBINES LOW ROLLING RESISTANCE WITH INCREASED GRIP, SEALSKIN PUNCTURE PROTECTION AND A SUPPLE 120 TPI RACE CASING FOR CONFIDENT PERFORMANCE ACROSS ROUGH AND UNPREDICTABLE TERRAIN.

The SILCA Protocol RCG-3 is a performance gravel tyre designed for riders who want race-level speed without sacrificing protection and control when conditions become rougher or less predictable.

Sitting between the fast-hardpack RCG-1 and more aggressive RCG-4, the RCG-3 uses a moderate directional tread pattern with tightly spaced centre knobs that progressively increase in size and height towards the shoulders. This provides efficient straight-line rolling while increasing tyre support, contact and grip as you lean through corners.

Combined with SILCA's Pulsar Compound, SealSkin puncture protection and high-volume 120 TPI Race Casing, the RCG-3 is an exceptionally versatile choice for Australian gravel racing and fast mixed-terrain riding.


KEY FEATURES

Fast Mixed-Terrain Tread
Tightly spaced, elongated centre knobs maintain efficient rolling, while progressively larger and taller knobs towards the shoulders provide additional grip and support through corners.

SealSkin Puncture Protection
An additional under-tread protection layer improves resistance to impacts and punctures on rough gravel without the heavy, sluggish ride traditionally associated with reinforced tyres.

Pulsar Compound
SILCA's performance rubber and silica compound is engineered to balance rolling efficiency, traction and durability for competitive gravel riding.

120 TPI Race Casing
A supple, lightweight casing delivers responsive ride quality while supporting the larger tyre volumes and pressures used by modern gravel bikes.

High-Volume Options
Available in 45 mm, 50 mm and 55 mm widths, allowing riders to choose their preferred balance of weight, comfort, traction and rough-surface capability.

Tubeless Ready
Purpose-designed for modern tubeless systems, allowing optimised pressures for improved traction, comfort and puncture resistance.


TECHNOLOGY

Pulsar Compound
A high-performance rubber and silica race compound developed to maintain rolling efficiency, grip and durability together rather than heavily compromising one characteristic to improve another.

Race Casing
SILCA's Race Casing architecture is developed around modern gravel tyre pressures and wider rims. The construction helps the tyre retain its intended shape and ride quality while delivering the supple feel and efficiency expected from a race-focused tyre.

SealSkin Protection
The RCG-3 incorporates enhanced under-tread puncture protection for demanding terrain. SealSkin increases resistance to impacts and punctures while minimising the internal friction that can make heavily protected tyres feel slow.

CarbonBead BeadLock
Carbon fibre bead technology provides dimensional stability throughout the tyre's service life, helping maintain consistent tyre dimensions after installation.

Progressive Tread Architecture
Tightly spaced centre knobs progressively increase in both size and height towards the outside of the tyre. This allows efficient rolling through the centre while creating a larger, more supportive contact patch as the bike leans into a corner.

Optimised Pressure Dynamics
The RCG-3 casing is designed to operate at a slightly higher baseline pressure than SILCA's lighter gravel race casing. This helps limit excessive casing deflection, stabilise the contact patch and increase pinch-flat protection while retaining traction and predictable handling.

Tubeless Ready Construction
Engineered from the bead upwards for modern tubeless systems, allowing tyre, rim, sealant and operating pressure to function together for optimum gravel performance.


WHY TO CHOOSE

The SILCA Protocol RCG-3 is the tyre to choose when your gravel riding demands more grip and protection than a fast hardpack tyre, but you don't want to sacrifice the speed and responsiveness of a race-focused setup.
Compared with the RCG-1, its more substantial tread and SealSkin protection make it better suited to rougher, more technical and less predictable terrain. The closely spaced centre tread still prioritises rolling efficiency, while the progressive shoulder design provides additional confidence as surfaces loosen and corners become more demanding.
For riders who regularly encounter changing gravel conditions and want one high-performance tyre capable of handling a broad range of terrain, the RCG-3 is arguably the most versatile option in the Protocol gravel range.


PERFECT FOR

Gravel racing, mixed-terrain riding, rough gravel roads, loose-over-hard surfaces, rocky sections and long-distance gravel adventures where both speed and puncture protection matter.
An excellent choice for Australian gravel riders dealing with changing surfaces and demanding conditions who want a fast tubeless tyre with greater grip and protection without moving to a heavily treaded gravel tyre.
