Ultradynamico’s Catalan Cava is a fine wine indeed. A minimalist tire for those who want the free speed of a high volume slick but need a tire that is more predictable in looser corners. Designed to be used as a pair, or as the rearcompliment to a Ros front tire for extra cornering and braking traction.
