Silca, renowned for its precision-engineered cycling accessories, has ventured into tire manufacturing with the introduction of the Protocol series—four meticulously crafted tires designed to redefine gravel and road racing performance. Addressing the industry’s need for high-volume, low-rolling-resistance tires that don’t compromise on grip or durability, Silca’s Protocol lineup offers a tailored solution for modern cyclists.
The Protocol Series: A Comprehensive Overview
The Protocol series comprises four distinct models, each engineered to excel in specific riding conditions:
- RCG-1: A low-profile gravel tire optimized for speed on hardpack surfaces.
- RCG-3: A medium-profile tire designed for mixed conditions, balancing speed and traction.
- RCG-4: A medium-profile tire with widely spaced knobs, ideal for loose terrains.
- RCR: A slick-profile road tire with subtle tread cuts, perfect for all-road adventures.
Innovative Design and Technology
Silca’s Protocol tires are distinguished by several innovative features:
- Tubeless-Ready Construction: Ensures a secure fit and reduced risk of flats.
- 120 TPI Race Casing: Provides a supple ride with enhanced responsiveness.
- Pulsar Rubber Compound: A high-performance solution-polymerized styrene-butadiene rubber with silica reinforcement, offering balanced rolling efficiency, grip, and durability.
- Variable Height Gravel Tread Knobs: Taller outer knobs engage earlier at gentler lean angles, maintaining traction, while asymmetrical patterns optimize braking and acceleration forces.
- Carbon Fiber Bead Reinforcement: Enhances dimensional stability and foldability, replacing traditional Kevlar/Aramid beads.
Size Options and Availability
The Protocol tires are available in various sizes to cater to different riding preferences:
- RCG-1: 700c x 45, 50, and 55mm widths.
- RCG-3: 700c x 45, 50, 55mm, and 32″ x 2.4″ widths.

Endorsements from Professional Cyclists
Professional gravel racer Dylan Johnson, a Silca-sponsored athlete, shared his experience:
“Throughout my career, I’ve avoided official tire sponsorships so I could strictly run whatever tested fastest in the lab and on the dirt. The Protocol lineup is the first time a tire checks every box for volume, traction, and speed, making this partnership with SILCA an easy decision.”
Silca’s Protocol series represents a significant advancement in tire technology, offering cyclists a blend of speed, durability, and versatility tailored to the demands of modern gravel and road racing.
