Ron, aka ULTRAROMANCE, and his old friend Patrick, aka ULTRATRADITIONAL, started this up-and-coming tire brand ULTRADYNAMICO . They believe that bicycles represent a relationship between practicality and artistic design, and that they are passionate about designing for high end rubber, which they have developed over years of riding over all terrains.

Believing that a bicycle is a collection of practical and artistic designs, representing the relationship between functionality and style, they have combined years of experience riding over all terrains, a passion for high-end rubber, a keen eye for design, and the scientific knowledge of a third grader to create a tire brand that is the first of its kind in the galaxy. The result is a tire that is designed to be the best gravel road tire in the galaxy.

And now the much-anticipated new pattern, MARS, has joined the lineup!

Sometimes you may find yourself a little off course and end up in a magical place like Mars. When that happens, if you wear these performance-tuned MARS tires for ATB, you will not only have a stylish look you can be proud to show everyone on NASA's live feed, but also enjoy a great ride at the same timE

By the way, there is a rich, nutty, fortified wine from Sicily called MARsala, which is a great wine to drink. If this tire is a hit, Ron and Patrick will have a rich, nutty aroma.

It is tubeless-compatible, so to get the best out of it, we recommend that you use it tubeless.

Its production is by Panaracer, the pride of Japan. How about a dynamic with function and beauty?


The race compound has excellent grip on all kinds of surfaces.

Tread rubber is extended to the sidewalls for improved protection without sacrificing the premium ride quality of the most flexible casing.

・Continuously varying center delta pattern provides quick turning for propulsion and secure braking traction for deceleration.

・Side sections grip well on loose or dry road surfaces.

The widely spaced knobs provide good mud shedding and leave artistic tire marks.

In the case of 27.5", you can enjoy the ATB Rat Rover by setting this MARS on the front and putting Cava or Rose on the rear.
