New! Silca Protocol RCG-1 Tubeless Gravel Bike Tire Black 700c 45mm-55mm

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 new Protocol RCG-1 tire 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 tire 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.
