Silca Protocol RCR Tubeless Road Tire
Description
Road tires have gotten wider without getting faster, and that's the problem the Protocol RCR sets out to solve. Silca's first road tire treats the modern wide-tire trend as an engineering opportunity rather than an excuse to add rubber, building the RCR around lower-pressure dynamics from the bead outward.
Instead of scaling up an old design and calling the extra weight durability, this one leans on air volume to do the impact absorption, so the heavy puncture layers come off and the casing stays supple.
The casing is a 120 TPI Race Casing architecture developed specifically around the pressures wide rims actually run, which is what keeps the tire holding its shape and ride quality instead of squirming when you drop pressure. The rubber is Silca's Pulsar compound, a rubber-and-silica race blend built to hold rolling efficiency, grip, and durability in balance rather than trading one for another. Flat protection comes from a Ghost Shield layer that's tuned to add security without dragging down rolling speed. It's a slick-profile tire with a cut-in tread pattern, aimed squarely at pavement, chip seal, and the kind of rough race surfaces you'd meet at Paris-Roubaix.... Read More
