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 rear compliment to a Rosé front tire for extra cornering and braking traction.  

JFF means Just For Fun, but not only for fun - these tires are equally equipped for long days locked in the pain dungeon as they are for a Sunday tour of Portland's vegan doughnut shoppes.

JFF is Ultradynamico's most accessible offering; think of it as the industry standard in terms of casing and rubber spec.  This is an approachable luxury- the cubic zirconia of their catalogue.

• 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.
• Carbon compound for longer tread wear
• Less susceptible to tread slashes than a true slick
• Leak free sidewalls
• Designed to be inflated/deflated to tastefully low pressures: 25-35 psi (650b); 30-40 psi (700c)
• Tubeless compatible
• Continuous centre negative dark space aeronautic deltas for pure intoxicating SPEED
