Silca Protocol RCG-1 Tyre

SILCA PROTOCOL RCG-1 Gravel Tire

The fastest gravel tire for going fast off-road.

The SILCA PROTOCOL RCG-1 is a race-focused gravel tire designed for riders who want maximum speed without giving up the control and comfort needed when the road turns to dirt.

Developed around modern high-volume tire sizes, the RCG-1 combines the rolling speed of a hardpack slick with the compliance and grip of an XC race tire. It is built specifically for fast gravel racing, mixed-surface courses and high-speed rides where every watt counts.

The secret is its dual-purpose tread design. A low-ramped directional centre tread minimises rolling resistance while providing additional braking grip. When the trail gets loose and you lean into a corner, the elongated side knobs engage to increase surface contact, grip and stability.

The result is a tire that rolls exceptionally fast on pavement and hardpack while providing confidence when the terrain becomes loose or technical. (SILCA)

Key Features

• Fastest Pulsar Compound – SILCA’s high-performance rubber and silica race compound balances rolling efficiency, grip and durability.
• Race Casing – 120 TPI construction developed around modern gravel tire pressures for a supple, fast ride.
• GhostShield Protection – Proprietary casing construction provides puncture protection without relying on heavy breaker layers.
• CarbonBead BeadLock – Carbon-fiber bead technology helps maintain dimensional stability and consistent tire width throughout the tire’s life.
• Tubeless Ready – Designed for modern tubeless systems and lower tire pressures.
• Ramped Centre Tread – Directional centre tread is optimised for low rolling resistance while providing additional braking traction.
• Elevated Side Knobs – Larger side knobs provide additional grip and stability when cornering on loose-over-hard surfaces.
• High-Volume Design – Increased tire volume delivers greater compliance and comfort while maintaining race-level performance. (SILCA)

Performance

In SILCA’s controlled laboratory testing, the RCG-1 recorded 25.8 watts, compared with 27.0 watts for the Schwalbe Thunder Burt and 29.6 watts for the Continental Dubnital. SILCA also reports that the RCG-1 is lighter than both benchmark tires in the tested configurations. (SILCA)

Ideal For

• Gravel racing
• Gravel Worlds
• SBT GRVL
• Dust Bowl
• Fast hardpack gravel
• Pavement-heavy gravel courses
• Mixed tarmac and dirt riding
• High-speed endurance gravel

The RCG-1 is particularly suited to Cat 1 and Cat 2 gravel racing, where maintaining high tempo while managing changing surfaces is critical. (SILCA)
