The Continental X King Pro Tection cross country racing tire is superfast thanks to medium height lugs and the revered Black Chili rubber compound. The lugs deliver a surprising good grip for a tire that rolls smooth and fast. It is pretty much self-cleaning thanks to the wide spacing of the lugs.
We know this tire is grippy and fast, but it has a quality needed to rely on in competition - durability thanks in part to the new Continental ProTection casing. The extra all-round puncture protection layer renders the casings especially durable and resists sidewall blowouts sharp rocks can dish out. This is because the Pro Tection belt extends under the tread and through the sidewall. This new belt is lighter and more puncture resistant than its DuraSkin predecessor. Rolling resistance and absorption has also significantly improved. This tire has the revolution Tubeless ready bead so it can be run tubeless with sealant so small punctures won't delay your ride or ruin your race.
The Black Chili compound is derived directly from Moto GP racing and offers lots of high end technology. It is essentially a blend of natural and synthetic rubbers. The natural rubber is mixed with 'nano' sized soot particles, who's surface properties are optimized to deform around surface objects and inconsistencies in the road for better grip. These small particles also form a tighter bond with each other improving compound strength for improved longevity and shear strength. Thanks to these polymers and carbon fillers, the Black Chili ends up being some of the strongest and most durable tread available as well as having the least amount of rolling resistance. The fillers also greatly reduce flatting.
