ULTRADYNAMICO is an up-and-coming tire brand started by Ron ( ULTRAROMANCE ) and his old friend Patrick ( ULTRATRADITIONAL ) .

They believe that a bicycle is a collection of practical and artistic designs, symbolizing the relationship between functionality and style, and they have combined their experience gained from years of riding over all terrains, their passion for high-end rubber, their keen eye for design, and their third-grade scientific knowledge to create ULTRADYNAMICO. The result is a tire that is designed to be the best gravel road tire in the galaxy.

CAVA / Cava, the second original ULTRADYNAMICO pattern, was created to be as good as Cava, a Catalan winE

The minimalist pattern was designed to provide riders who want to ride with the wind on a voluminous slick tire, with the added bonus of being able to ride comfortably in slick corners and on some gravel.

The tire's lightweight sidewalls and unique race compound, which are designed for pure rolling lightness and to bring out the tire's suppleness without regard to durability, give riders the best ride comfort when riding gravel.

The front and rear can be used as a pair, or a more aggressive combination of Rose in the front and Cava in the rear is also recommended.

Since they are tubeless compatible, we recommend using them in a tubeless configuration to bring out the best in them. (We recommend that you use a good sealant because the side casing is quite thin.)

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

In June 2020, the long-awaited 700C x 42.? mm lineup has also been added!


The new "Stradivarius" is a pavement and dirt track shoe that is designed to be used on both paved and unpaved surfaces, just like a musician playing a Stradivarius.

The tire is made with a race compound that provides excellent grip on all surfaces.

Lightweight sidewalls for pure speed and suppleness, with no regard for protection.

Delta pattern designed for aerodynamics and traction on dirt roads.
