The Ultradynamico Mars Rozzo is built for riders who push beyond gravel and into true all-terrain riding. Designed as a high-volume ATB tyre, the Mars combines aggressive traction with surprisingly efficient rolling, making it equally at home on rough trails, dirt roads, and loaded bikepacking routes. At the centre is a continuous ramped delta tread, engineered for fast rolling under power while delivering strong, controlled braking when needed. The pronounced side knobs provide confidence in loose corners, while the wide spacing between knobs helps shed mud and maintain grip in changing conditions. The Rozzo casing is the most durable construction in the Mars lineup, featuring reinforced sidewalls and bead support for low-pressure riding without burping. It’s built for rugged terrain, heavier loads, and riders who prioritise reliability over outright weight savings.
