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 Ros 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 Ros, giving it the same effective outside diameter, leaving geometry unchanged when pairing with Ros up front -Race compound for superior grip in dry conditions -Less susceptible to tread slashes than a true slick -All of our highest end tires feature luxuriously high TPI mystery casing of varying hues, much like the fine wines of their namesakes -Zero sidewall protection for premium ride quality- get AAA if you plan on loaded touring with these over sharp, rugged terrain... or bring an extra -Leak free sidewalls -Designed to be inflated/deflated to tastefully low pressures: 25-35 psi (650b) 30-40 (700c) -Tubeless compatible -Continuous center negative dark space aeronautic deltas for pure intoxicating SPEED. -Tires packaged and sold individually -650b x 47.99mm, 700c x 42.??, 700c x 33.?? -490g and 445g
