The Ultradynamico Mars JFF is Ultradynamico's all-terrain tire — a knobby designed for riders who occasionally (or intentionally) veer off-road. The continuous ramped centre delta rolls fast when propelled and brakes confidently when modulated, while side knobs keep you upright in loose, dry corners. JFF stands for Just For Fun — equally equipped for long days in the pain dungeon as for a leisurely Sunday ride. Race compound throughout.
JFF casing: an intermediate option — still unprotected sidewalls, but thicker and more durable than the Race. Tread rubber extends down the sidewall for a little added protection. For more protection, consider the Robusto or Rozzo casing options. Tubeless compatible. Sold individually, FSC recyclable cardboard.
Tread: continuous ramped centre delta + side knobs
Casing: JFF (unprotected sidewalls, more durable than Race)
