Ultradynamico Cava JFF 650b Black/Tan


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.

  • 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 our 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 our 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 (normal) tread wear
  • JFF more durable casing than our RACE offerings. Fixing flats, while character building, has never been fun
  • Less susceptible to tread slashes than a true slick
  • Zero sidewall protection and no puncture protection on top for premium ride quality
  • Leak free sidewalls
  • Designed to be inflated/deflated to tastefully low pressures: 25-35 psi (650b); 30-40 psi (700c)
  • Tubeless compatible
  • Continuous center negative dark space aeronautic deltas for pure intoxicating SPEED
  • 650b x 47.99mm and 700c x 42.??mm available
  • Black and Tan sidewalls available, JFF
  • Tires packaged and sold individually
  • 510g and 465g
