Distilled directly from the Ultradynamico website:
Our 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 rear compliment to a Rosé front tire for extra cornering and braking traction.
-3D diamond file tread massages granular terrain for perceivably 20-30% more traction than a slick
-Slightly higher volume than the Rosé, giving it the same effective outside diameter, leaving geometry unchanged when pairing with Rosé up front.
-High carbon brevet compound for longer (normal) tread wear
-Less susceptible to tread slashes than a true slick
-Robusto sidewall protection for touring and the flatphobic gravel guzzler
-High TPI mystery casing underneath that Robusto, BTW
-Robusto means you can ride CERTIFICATION free.
-Leak free sidewalls
-Designed to be inflated/deflated to tastefully low pressures: 25-35 psi (650b); 30-40psi (700c)
-Continuous center negative dark space aeronautic deltas for pure intoxicating SPEED
-Tires packaged and sold individually
-650b x 47.99mm
