ULTRADYNAMICO BRUT JFF TYRES

The Ultradynamico Brut 29" × 2.1 JFF sits between the Cava and the Rosé in tread depth — designed for fast, dry terrain where you want something smoother than a knobby but with more bite than a near-slick. Tightly spaced micro triangles that sparkle on pavement and grip when you tip onto singletrack. JFF stands for Just For Fun — but equally equipped for long days in the pain dungeon as for a leisurely Sunday ride. Race compound throughout.

JFF casing: an intermediate option — no sidewall protection, but thicker and more durable than the Race casing. Tread rubber extends down the sidewall for a little added coverage. For more protection, consider the Robusto or Rozzo casing options. Tubeless compatible. Sold individually, FSC recyclable cardboard.
