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. -3D diamond file tread massages granular terrain for perceivably 20-30% more traction than a slick -Continuous center negative dark space aeronautic deltas for pure intoxicating SPEED -Slightly higher volume than the Rosé, giving it the same effective outside diameter, leaving geometry unchanged when pairing with Rosé up front. -Less susceptible to tread slashes than a true slick -Robusto sidewall protection for getting rowdy on the one-track, touring and the rambunctious, rugged chunk guzzler. -High TPI mystery casing underneath that Robusto, BTW -Leak free sidewalls -Tubeless compatible -Tires packaged in nice, FSC, recyclable cardboard and sold individually ***700c x 38.??*** We designed this tire to be a large volume ROAD tire suitable for light, groomer dirt roads, but at this low volume we don't really think of it as a gravel tire. The sizing is sorta funny, it is badged a 700c x 39, but on most modern rims it's been measuring a little smaller upon initial mounting, more like a 37-38mm but after some use these stretch out to almost a 39mm width. *By Ultradynamico
