Silca Protocol RCR Road Tyre

The cobbles of Roubaix, your local chip seal roads, or the crit course, the RCR is ready to tackle the challenge. Pulsar compound and our Race Casing make the fastest road tire in the size. Bigger doesn't have to be slower.

RCR Architecture - A volume-centric approach that prioritizes width and speed without adding useless bulk, built around lower pressures associated with modern ride rims. It is the first road tire in this size range designed and optimized with the same care as a racing tire, thinner, faster, and more supple.

Performance Data - Against the Vittoria Corsa Pro Control 38mm, the RCR rolled at 31.7 watts in controlled lab testing versus the Vittoria's 40.5, saving nearly nine watts at the same width. It does it 70 grams lighter per tire, which is 140 grams off the wheels on a pair.

Ideal Conditions - From local criteriums to the punishing cobbles of Paris-Roubaix. The increased air volume absorbs impacts and reduces flat risk, making it the answer for rough pavement and long days where comfort holds your speed together.

• Pulsar Compound - A high-performance rubber and silica race compound engineered to hold rolling efficiency, grip, and durability in balance rather than trading one away for another.
• Race Casing - A race casing architecture developed around modern tire pressures, so the tire keeps its shape and its ride quality at the pressures wide rims actually run.
• CarbonBead BeadLock - Carbon fiber bead technology that keeps the tire dimensionally stable across its whole life, so the width you measure at installation is the width you keep.
• Tubeless Ready - Engineered for modern tubeless systems from the bead out, so sealant, valves, and lower pressures all work the way they were meant to.
