Silca Protocol RCG-3 700c Tire Speed With a Safety Net Mixed and unpredictable gravel is where the RCG-3 earns its keep. This is the tire for courses where you do not know exactly what the day holds: packed sections that give way to loose gravel, rough chunks that punish thin casings, and long stretches where a flat kills your day faster than any competitor. The RCG-3 takes XC mountain bike tire DNA and remaps it for modern gravel, with a moderate directional tread that keeps rolling resistance in check without giving up grip when the surface gets loose. An under-tread puncture breaker adds a layer of flat protection that is genuinely tested, not just claimed. The carbon fiber bead keeps the tire dimensionally stable over its lifetime so the width you set up with is the width you keep. This is the tire you reach for when the race brief says "Category 3 gravel" and the course proves it. Features Moderate directional tread pattern tightly spaced center knobs maintain rolling speed on hardpack while shoulder knobs engage for grip when surfaces turn loose Pulsar Compound high-performance rubber and silica race compound that holds rolling efficiency, grip, and durability in balance without trading one away for another Seal Skin Protection Layer under-tread puncture breaker selected for superior impact resistance, adding flat protection without the weight penalty typical of reinforced casings Carbon Bead Lock bead rigid carbon fiber bead that does not stretch or creep over time, keeping the tire dimensionally stable and reducing blowoff risk on hookless rims 120 TPI race casing supple, high-volume architecture developed around modern wide-rim pressures so the tire holds its shape and ride quality where you actually run it Tubeless-ready, hookless-compatible engineered for modern tubeless setups from the bead out Specifications Size700c Width(s)45mm, 50mm, 55mm Compound Pulsar Compound Casing Race Casing with Seal Skin Protection Layer (120 TPI)TPI120Bead Carbon Bead Lock (folding, carbon fiber)Tubeless Compatible Yes Hookless Compatible Yes Weight495g (45mm), 540g (50mm), 590g (55mm)Intended Use Gravel | Silca | Protocol Rcg-3 700C Tire 700X45, Race Casing | Rubber
