SILCA, renowned for its precision-engineered cycling accessories, has unveiled the Protocol tyre lineup, marking its inaugural foray into tyre manufacturing. This innovative range encompasses three gravel models and one high-volume road tyre, each meticulously crafted to enhance performance across diverse terrains.
Protocol RCG-1: Fast Hardpack & Mixed-Surface Gravel
Designed for high-tempo Category 1 and 2 gravel events, as well as mixed tarmac and dirt routes, the RCG-1 features a low, ramped directional centre tread paired with elevated, elongated side knobs. This configuration delivers rolling speed akin to a slick tyre while providing immediate cornering bite when leaned over. (news.twotoneams.nl)
Protocol RCG-3: All-Around Rough Terrain Gravel
Tailored for demanding Category 3 courses like Unbound and Big Sugar, the RCG-3 boasts tightly spaced centre knobs that increase in size towards the shoulder. It incorporates a low-friction under-tread puncture breaker and is tuned for a baseline inflation pressure approximately 8% above standard race tyres to prevent over-deflection, stabilise the contact patch, and eliminate pinch flats without sacrificing speed.

Protocol RCG-4: Adventure, Mud & Loose Trail
The ultimate off-grid tyre for sloppy mud, sand, and loose rock, the RCG-4 utilises aggressive, widely spaced lugs that shed sticky loam and mud in severe weather. It features full bead-to-bead puncture protection to guard against sidewall cuts on singletrack and unmaintained roads. (news.twotoneams.nl)
Protocol RCR: High-Volume Road
Built to eliminate unnecessary weight in modern wide road tyres, the RCR leverages increased air volume to handle impact absorption rather than heavy rubber layers. The 29mm variant is optimised for modern 25mm internal hookless rims to meet ETRTO standards without safety vulnerabilities, while the flagship 38mm model maximises volume within UCI regulation limits for ultra-fast, supple pavement and cobble performance.
