{"title":"Gravel Tires","description":"For years, the industry treated gravel tires like oversized road tires, adding heavy casings as volume increased. Our gravel bike tires start with an XC mountain bike tire design distilled to essentials, built on high-volume 120 TPI casings and variable-height tread. RCG-1 for fast hardpack, RCG-3 for mixed terrain, RCG-4 for mud and loose rock.","products":[{"product_id":"protocol-rcg-1-gravel-tire","title":"Protocol RCG-1 Gravel Tire","description":"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.  \n\u003cbr\u003e\u003cbr\u003e\nLook 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.
