Ultradynamico's ATB masterpiece, the MARS(ala), is the finest cross country rubber slippers out at the moment. The ramped center triangle pattern offers continuous fast easy rolling, while the outer knobs allow you to dive hard into loose dusty corners out on the trail. The widely spread tread pattern offers superior mud ejection. The MARS comes in three compounds: Race- It is the one and only gray tire that only comes in gray. Its the lightest of the casings. If you tend to flat a lot, you may want to consider getting the Robusto casing. The Race compound is the pinnacle of ride feel and grip in all conditions. As supple as a cloud floating on buttered ice, with the grip of Over the Top protagonist Lincoln Hawk. JFF- The Just For Fun casing is the middle of the road bang for your buck tire. Seriously, the value of this tire is outrageous. If you're looking to dip your toes into the silken rubber market, but you're not quite ready to spend the full $85 on a tire, the JFF will give you that premium feel at a fraction of the price. Robusto- The Robusto casing offers up the most protection of the three casings. This is the perfect choice if you are prone to flatting, are concerned with getting sidewall slashes, or are planning on taking these tires on tour.
