Ultradynamico Korea | Ultradynamico Bicycle Tires

Useful is not
enough.
It has to be beautiful.

Ultradynamico is an American tire brand made by two old friends and self-described tire fetishists, Ron (Ultraromance) and Pat (Ultratradition). To them the bicycle is where utility meets artistic design, so a tire's ride and its looks matter equally.

After nearly fifty years of combined tread awareness, they had grown numb to garish logos, bizarre tread patterns and overbuilt, lifeless casings. Years of all-terrain riding, a passion for high-end rubber, an eye for design and a dash of third-grade science led them to make their own. The startup funds came from selling some long-forgotten stock.

The speed of a slick,
trust in the corners.
Like a fine Catalan Cava.

Cava is a minimalist tread for riders who want the free speed of a high-volume slick but need a tire that is more predictable in loose corners. Its 3D diamond file tread massages granular terrain for a perceived 20 to 30% more traction than a slick.

A continuous center of delta shapes keeps rolling resistance low, and it is less prone to tread slashes than a true slick. It pairs well in the rear with a knobbier Rosé or Mars up front. The 700C x 33 is a road classics tire for the cobbles and short dirt sectors of Flanders, not a gravel tire.

Smooth on pavement,
a little more bite in the dirt.
Between Cava and Rosé.

Brut was dreamed up with fast, dry terrain in mind, and its tread depth lands between Cava and Rosé. The goal was a tire that rolls smoothly on pavement yet bites a little more than Cava in the dirt.

Tightly spaced micro triangles sparkle on asphalt, and once tipped onto singletrack they give confident braking traction and grip. Tread rubber extends down the sidewall for a little added protection without spoiling the ride of the lightest, most supple Race casing. Brut means almost no sugar, yet this is a very sweet tire.

The first tire,
the mainstay of the range.
Pavement and dirt alike.

Rosé was Ultradynamico's first tire and is still the mainstay of the range. It handles pavement and dirt like a skilled musician handles a Stradivarius. A near-continuous center tread drives you forward, and delta knobs deliver braking traction when you re-enter the gravel.

After about 1,000km, a file-pattern undertread hidden beneath the knobs is revealed. This tire actually gets faster with age. Run Rosé front and rear for maximum off-road traction, or swap the rear to Cava to drift the corners a little more.

Veer slightly off course,
and you end up
in a place like Mars.

Mars is the knobbiest tread in the range, designed by riders and tuned for ATB performance. A ramped, continuous center delta rolls fast when you pedal and brakes with confidence when you modulate.

Side knobs won't let you down in loose, dry corners, and wide knob spacing sheds mud while leaving artistic patterns in the dust. The name comes from Marsala, the fortified wine of Sicily. With a 26 inch option, it suits classic MTB rebuilds too.

The casing is the skeleton of a tire,
its heart and soul.

A tire's ride quality, liveliness and personality all come from its casing. Ultradynamico makes every one of its four treads in four casings. From the lightest, most supple Race to the Robusto that handles anything, choose by your riding style and your roads.

Tires made
by two friends
fussy about tires.

There was no grand plan. They wanted to make one tire that didn't exist, and figured that even if no one bought it, the two of them could use it for life. That small company now makes four treads in four casings, across more than thirty specs.
