Ultradynamico BRUT JFF Tyre
The Ultradynamico Brut JFF sits right between the Cava and Rosé — delivering a refined balance of speed, grip, and everyday usability. Designed for high-speed riding on dry mixed terrain, the Brut brings a more aggressive bite than a semi-slick, while remaining smooth and efficient on pavement.
Its defining feature is a dense micro-triangle tread pattern, engineered to roll fast on hard surfaces while providing strong braking traction and control on dirt, gravel, and technical sections. Compared to the Cava, the Brut offers more grip and stability; compared to the Rosé, it maintains better rolling speed and efficiency.
Built with the JFF (Just For Fun) casing, the Brut strikes a balance between performance and durability. It uses a slightly thicker, more robust construction than Race casings, offering improved longevity and everyday reliability while still retaining a supple ride feel.
