Ultradynamico Mars JFF

In stock (2)

These tires are built different! Try Ultradynamico's out and you'll see why. Stick out from the pack and get them at Bike and Brew. JFF stands for Just For Fun.


Sometimes you veer slightly off course and end up in a place like MARS.  If you are running our rider-designed, ATB performance tuned rubber, you'll not only be styling for the NASA livestream, but you'll also be in for a great ride.  Marsala also happens to be a rich and nutty fortified wine from Sicily.  If these tires sell, Patz and Ron will be both rich and nutty.

-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 shops.

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

-JFF more durable casing than our RACE offerings.  Fixing flats, while character building, has never been fun

 -Continuous ramped center delta for a fast roll when propelled, and confident braking traction when modulated.

-Side knobs won't let you down, or let you fall down in loose, dry corners.

-Wide knob spacing sheds mud and makes artistic patterns in the space dust.

-Tread rubber extended down sidewall for added protection without sacrificing the premium ride quality of our flexible casings.

-27.5 pairs as a front with our Rosé or CAVA 650b in the rear for a fast and fun slackened ATB rat-rover.

-Special edition MARS dirt infused compound for 26" release.

-Tubeless compatible for a rover mimicking psi of 20-30psi.

-620g and 610g
