Ultradynamico Cava JFF 700x42.??

£ 55.00 GBP
(Ex VAT)
Ultradynamico Tyres are made by our friends Pat and Ron. Here's what they have to say: “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.” If your route leaves the road then you'll struggle to find tyres better equipped to help you enjoy your ride. The range is comprised of three different tread profiles (Cava, Rosé, Mars) and three separate carcass weights (Race, JFF, Robusto). We stock a selection of the best all round tyres that Ultradynamico produce. We keep a small stock of these models, delivery may take a couple fo weeks if we are out of stock at the time your order is placed.

Ultradynamico Cava JFF 700x42.??

Pat and Ron say:

"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: 30-40 psi

-Tubeless compatible

-Continuous center negative dark space aeronautic deltas for pure intoxicating SPEED

-Tires packaged and sold individually
