ULTRADYNAMICO Mars JFF

ULTRADYNAMICO is an up-and-coming tire brand founded by Ron—also known as ULTRAROMANCE —and his longtime friend Patrick, also known as ULTRATRADITIONAL.

Believing that bicycles are a fusion of practical and artistic design—symbolizing the perfect balance between functionality and style—they drew upon their years of experience riding across all terrains, their passion for high-end rubber,sharp design insight, and elementary-school-level scientific knowledge to create tires capable of riding the galaxy’s best gravel roads.

Sometimes you might veer slightly off course and end up in a mysterious place that looks like Mars. In such moments, if you’re riding this performance-tuned “Mars” tire designed for ATBs, you’ll not only have the style to be proud of—even if you appear on a NASA live stream—but you’ll also enjoy an amazing ride.

By the way, there’s a fortified wine from Sicily called MARsala that has a rich, nutty aroma. If this tire becomes a hit, Ron and Patrick will probably start smelling rich and nutty themselves.

The JFF grade offers greater durability than the Race grade and uses a unique compound to provide riders with a supremely comfortable ride on gravel.

Since it’s tubeless-compatible, we recommend using it tubeless to get the most out of it. It’s manufactured by Panaracer, a brand Japan is proud of. How about experiencing this dynamic tire that combines function and beauty?

You may notice slight color variations on the sidewall; this is a normal product characteristic, and we ship these items as standard. We appreciate your understanding. Additionally, the shade of the casing may vary by model, such as Rose or Cava.
