SILCA PROTOCOL RCR Road Tire Bigger doesn’t have to be slower. The SILCA PROTOCOL RCR is a high-performance road racing tire designed around modern wider rims, higher air volume and lower tire pressures. Rather than simply making traditional road tires wider and heavier, SILCA developed the RCR around a volume-centric design that prioritises speed, comfort and efficiency without unnecessary weight. From smooth tarmac and chip-seal roads to demanding race courses and Paris-Roubaix-style cobbles, the PROTOCOL RCR combines a supple race casing with SILCA’s fastest Pulsar Compound to deliver a fast, responsive and comfortable ride. The increased air volume allows the tire to absorb impacts and reduce the risk of flats, while the lightweight construction keeps rolling performance high. Key Features Pulsar Compound – SILCA’s fastest high-performance rubber and silica race compound, balancing rolling efficiency, grip and durability. Race Casing – A supple 120 TPI casing designed around modern lower tire pressures and wider rims. CarbonBead BeadLock – Rigid carbon-fiber bead technology prevents stretching and helps maintain a consistent tire fit over time. SealSkin Tread Protection – Added protection designed to improve durability without compromising the tire’s race-focused characteristics. Tubeless Ready – Optimised for modern tubeless systems and lower-pressure riding. Volume-Centric Design – Increased air volume provides improved comfort, impact absorption and flat resistance without excessive casing weight. 25mm Internal Rim Optimisation – The 29mm version is specifically designed around a modern 25mm internal-width rim. Performance SILCA tested the 38mm PROTOCOL RCR at 31.7 watts against a Vittoria Corsa Pro Control 38mm at 40.5 watts in controlled laboratory testing, while the RCR was also reported to be 70g lighter per tire. (SILCA) The result is a high-volume road tire that combines the comfort and impact absorption of a wider tire with the speed and responsiveness expected from a race tire. SILCA PROTOCOL RCR — high-volume performance without the weight penalty.
