Silca Protocol RCG-1 Folding Gravel Tyres With Silca Ultimate v2 500ml Tubeless Sealant - Pair
When speed off road is the goal, Protocol RCG-1 is the go to option. The first ever gravel tire that was developed around modern sizes first. RCG-1 is the fastest option available for the biggest races.
Unfair advantage? Maybe. Silca’s Protocol RCG-1 tyre pairs the rolling speed of a hardpack slick with the high-volume compliance of an XC race tire. From Cat 1 and 2 Gravel races like Gravel Worlds or SBT GRVL, where tempo and comfort are paramount, the RCG-1 tyre is designed to push the limits of fast gravel racing by balancing speed with control. It’s also at home on mixed surface rides that regularly transition between tarmac and dirt.
Look down the center and you’ll see a low ramped directional tread transition for forward rolling efficiency with a braking surface that bites hard when slowing down. Approach a loose, high-speed sweeping corner, and its elevated, elongated side knobs engage to maximize surface area to deliver grip and stability. It is a dual-personality tread that rolls like a slick in a straight line, yet delivers cornering confidence the moment you lean the bike.
RCG-1 Architecture
Look down the centre, and you will see a low-ramped directional transition built for forward rolling efficiency, with a braking surface that bites hard when you slow down. Approach a loose, high-speed sweeping corner and the elevated, elongated side knobs engage to maximize surface area for grip and stability.
Testing/Performance Data
Measured against the Schwalbe Thunder Burt and the Continental Dubnital, the RCG-1 rolled fastest in controlled lab testing at 25.8 watts, ahead of both at 27.0 and 29.6. It also comes in 125 and 85 grams lighter per tyre, beating the leading XC benchmarks on speed and weight at the same time.
Ideal Conditions
Cat 1 and 2 gravel races like Gravel Worlds, SBT GRVL, and Dust Bowl, where tempo and comfort are paramount. They're equally at home on mixed-surface rides that regularly transition between tarmac and dirt.

Silca Ultimate v2 Tubeless Sealant - 500ml
Injectable through your valve, seals a 6mm+ puncture, and lasts up to 6 months. The perfect sealant for those looking for the ultimate sealing power, longevity, and ease of use.
The original sealant formulation, released 2.5 years ago, was designed primarily for effective puncture sealing by maximizing the surface area of the liquid latex for enhanced performance. Pro racers valued its convenience, as they frequently changed tires based on race conditions and could easily pour in fresh sealant without needing to inject it through the valve. However, we heard two main concerns from more casual cyclists—it dried out quickly when not in use, and its composition of the longer strand carbon fiber made injection difficult and problematic, leading to a potentially messy installation if not handled carefully.
Lastly, the old Natural Latex formula needed a two-step process to stay liquid longer. That has been eliminated with our new blend of natural and synthetic latex. SILCA Ultimate Sealant Is a one-step process lasting +6 months and still, above all else, sealing punctures on race day.
