The 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. The 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 the Ultradynamico catalogue.

The 3D diamond file tread massages granular terrain for perceivably 20-30% more traction than a slick. A 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 (normal) tread wear. The JFF has a more durable casing than the RACE offerings. Fixing flats, while character building, has never been fun.

About Ultradynamico

ULTRADYNAMICO founders and tire fetishists, Pat and Ron, believe everything in life should not only be functional, but above all, beautiful. The bicycle is the synthesis of utilitarian artistic design; representing the nexus of function and style. Essentially: ride attributes share equal importance with aesthetics.

With a combined fifty years of tread awareness between them, Pat and Ron went numb. Garish logos, bizarre looking tread patterns, and overbuilt, lifeless casings were flooding a market already mired in tepid options, leaving few choices for true tire aficionados.

A confluence of extensive all-terrain riding experience, passion for high-end rubber, keen eyes for design, and a dash of 3rd grade science led to the birth of a tire and component company built entirely on passion, raw need, and startup funds from the offloading of some long lost Amgen stock.

"We design tires that will carry you beyond cul de sac country backroads and into a galactic-premium-ground-gravel realm of enlightenment. Tires for the CONNOISSEUR."

It's no secret that tire choice fundamentally dictates the aesthetic of your build and this choice is the ultimate expression of performance and beauty. We all know your bicycle is an extension of your personality, your riding style a window into your soul. In a world paralyzed by dull and mediocre options we invite you to choose dynamically.

"Skip a few meals and buy our tires, you deserve it."

Note: Tubeless Ready tires require tubeless compatible rims/wheels, tubeless valves, tubeless rim tape and sealing fluid for tubeless mounting. Sealant fluid is not required for tubeless UST tires, but is recommended for increased puncture protection. Installation should only be carried out by qualified personnel.
