ULTRADYNAMICO Rose Rozzo

Flexible yet durable. A gravel tire that’s fun to ride even at low pressure

ULTRADYNAMICO is a tire brand founded by Ron—aka ULTRAROMANCE —and his longtime friend Patrick—aka ULTRATRADITIONAL. Having ridden everything from paved roads to dirt trails, the two have packed the joy of riding and their unique style into these tires.

The “Rose” is the brand’s first original tread pattern. The nearly continuous row of tread blocks in the center supports a smooth, responsive roll, while the unique delta-shaped knobs provide solid performance for braking and cornering on dirt. From paved roads to gravel and dry singletrack, this is a tire that will make you want to take a detour.

Among the Rose lineup, the Rozzo is designed with durability as a top priority. In addition to sidewall protection, the bead area is reinforced. It’s engineered to minimize tire flex when riding at low pressure and prevent air leaks around the bead. The tread rubber extends to the sides, further strengthening protection around the shoulders.

It features the Race compound, which prioritizes grip and speed. We also recommend pairing the supple Race on the front wheel with the highly durable Rozzo on the rear. If you want to ride comfortably on rough terrain, this reliability really comes into its own.

*Note: You may notice slight color variations on the sidewall; this is a normal part of the product’s specifications. The shade of the sidewall may vary by model, such as Rose or Cava.
