Ultradynamico Mars JFF Folding Tire - 29 x 2.3" - black

Sometimes you veer off course a bit and end up in a place like MARS. When you ride the rider-designed rubber tuned to ATB, you'll not only be styled for the livestream of NASA, but also for a great ride. MARsala is also a rich and nutty fortified wine from Sicily. If these hoops sell, Pat and Ron will be both rich and nutty.

JFF means Just For Fun, but not just for fun - these hoops are as suitable for long days in the pain dungeon as they are for a Sunday tour of Portland's vegan donut stores. JFF is the most accessible offering; consider it the industry standard in terms of casing and rubber specs. The JFF casing is even more durable than that of the RACE models. Repairing flats has never been more fun.

Features of the Mars JFF folding tire

• Continuous ramp delta in the center of the tire for quick roll off when propelling and sure stopping traction when braking.
• Lateral lugs won't let you down or tumble in loose, dry corners.
• The wide tread spacing deflects mud and creates artful patterns in the dust of the landscape.
• Did you know that the triangle is the strongest shape in this dimension?
• Tread rubber on the sidewall adds protection without compromising the premium ride quality of the flexible carcasses.
• Can be combined on the front wheel with the ROSé or CAVA 650b on the rear wheel for a fast and fun ATB ratrover with loosening effect.

• Tubeless compatible for a Rover mimicking pressure of 20-30psi.

About Ultradynamico

ULTRADYNAMICO's founders and tire fetishists, Pat and Ron, believe that everything in life should be not only functional, but above all beautiful. The bicycle is the synthesis of useful, artistic design and represents the marriage of function and style. In essence, the riding characteristics are equally important as the aesthetics.

With a combined fifty years of tire tread experience, Pat and Ron are jaded. Garish logos, bizarre-looking tread patterns, and over-constructed, lifeless casings flooded a market already awash in lukewarm options, leaving true tire lovers with few choices.

The confluence of extensive off-road experience, a passion for high-quality rubber, a keen eye for design and a dash of third-grade science led to the creation of a tire and component manufacturer built solely on passion, raw needs and seed money from the sale 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 the choice of tire has a significant impact on the aesthetics of your bike, and that this choice is the ultimate expression of performance and beauty. We all know that a bike is an extension of your personality, your riding style a window to your soul. In a world paralyzed by boring 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.
