Protocol RCR Tubeless 700c Road Tire

The SILCA Protocol RCR is a high performance tubeless road tire designed for riders who want a fast, supple tire without having to stick to perfectly smooth pavement. It combines a lightweight 120 TPI Race Casing with SILCA's Pulsar rubber compound and a higher volume design that works especially well with the wider rims and lower tire pressures common on modern road bikes.

The RCR is available in 29, 34, and 38mm widths, giving riders the option to prioritize outright speed or add more air volume and comfort. The 29mm version makes a strong choice for fast road riding and racing, while the wider versions are well suited to endurance riding, rough pavement, and roads where a little extra cushioning can make a big difference.

The 120 TPI Race Casing is designed to keep the tire supple and responsive rather than relying on heavy construction to provide impact protection. More air volume helps the tire absorb bumps and impacts, while the casing can remain light and flexible for the low rolling resistance and lively ride quality you expect from a high end road tire.

SILCA's Pulsar compound is designed to balance low rolling resistance with grip and durability. The RCR also uses CarbonBead BeadLock technology and SealSkin tread protection for a secure fit and added protection against everyday road hazards.

Why We Like It The Silca RCR hits a sweet spot between a pure race tire and the wider, more comfortable road tires that have become popular on modern bikes. It still has the quick, supple feel we want from a fast road tire, but the additional air volume makes rough pavement considerably easier to deal with. If you want a tubeless road tire that feels fast without requiring perfect roads, the RCR is a really compelling option.
