The up-and-coming tire brand ULTRADYNAMICO was started by Ron (aka ULTRAROMANCE) and his long-time friend Patrick (aka ULTRATRADITIONAL).
Believing that a bicycle is a collection of practical and artistic designs that symbolize the relationship between function and style, they combined their years of experience riding through every type of terrain, a passion for high-end rubber, keen design insight, and scientific knowledge rivaling that of a third-grader to design a tire capable of handling the most gravel-ready roads in the galaxy.
Not just tires, but unique soft goods too
They put just as much care into their soft goods as their tires, and we’ve just received their latest merchandise!
ULTRADYNAMICO Rubber Man T-Shirt
Size: S, M, L
Price: ¥5,060
A soft 100% organic cotton T-shirt.
The clever design is by Casey Robertson. He is an artist in the know who has worked on many illustrations for Ultradynamico and other California bicycle companies.
It’s a total homage, or respect, or rip-o—ahem, ahem… well, there are many ways to put it, but it’s a cute(?) design of Ron dressed as a certain Michelin-related man.
The soft cotton fabric is comfortable to wear. We recommend a somewhat tighter fit.
ULTRADYNAMICO Nice T-Shirt
Size: S, M, L
Price: ¥4,400
A soft recycled cotton T-shirt featuring the Ultradynamico logo on the front.
It is screen-printed by Shirt Shark in Clinton, CT, near the barn where they store their rubber.
With its simple logo and body, this shirt is easy to match with any pair of pants and is a must-have for Ultradynamico fans.
ULTRADYNAMICO Alt Font Cap
Size: Free
Price: ¥4,290
A cap featuring a simple print of the Ultradynamico logo. A green color has been added. You can never have too many cycling caps, so consider adding this to your collection.
Tires are back in stock too!
Ultradynamico is one of the most popular tire brands here at Circles.
I’m sure many of you are repeat buyers of tires with such unbeatable tread patterns.
These are tires that will carry you beyond country lanes to premium gravel roads in the galaxy.
A bicycle is an expression of personality, and tires are what make that personality stand out even more.
Once you install them, you’ll be hooked on Ultradynamico, and it will become a companion that reflects your own unique personality.
Simply put, if you’re hesitating, you have to try them!
Let’s finish by borrowing their own words.
“Skip a few meals and buy our tires, you deserve it.”
