For an interstellar feel look no further than the MARS. A space age ATB tire with a classic look. From the cobblestone streets of Old City, Philadelphia to the gravel backroads of Minnesota, to the rocky trails of the Southwest. This tire is ready for it all!

-JFF means Just For Fun. But don’t let that fool you, these tires are ready to be put to work!

-JFF is the entry level tire of the Ultradynamico line up. It has also been called a mid category. Thicker than the Race and lighter than the Robusto.

-”Continuous ramped center delta” for a fast, uninterrupted ride, and increased braking traction when modulated

-Side knobs to let you cut through loose, dry corners.

-Wide knob spacing helps to shed mud and leave an artistic pattern in the dust.

-Triangular tread pattern for added strength and speed.

-Tubeless compatible with optimum psi of 20-30

-Available in 27.5” x 2.2?? or 29” x 2.2??

-What do those question marks mean??? Think of it as sort of an inside joke. The tires you have now are probably lying to you. That’s because a tires width varies with each rim. Something a wheel builder could tell you about if only you knew where to find one…

-620g (29”) and 610g (27.5”)
