Geometry and dimensions

The Z Box S features a height of 140 mm with dimensions of 75 x 75 mm at the base, integrating perfectly with modern frame geometries. This compactness makes it the ideal size for short to medium rides, without sacrificing space for a second hydration bottle. The cylindrical profile ensures smooth insertion and extraction, even while riding.

Materials and construction

Made from high-quality technical polypropylene, the Z Box S resists impacts, vibrations and the mechanical stresses of off-road cycling. The material offers proven robustness while maintaining optimal lightness. The screw closure system ensures a watertight and reliable seal, tested over thousands of kilometers by Zéfal's development teams.

Usage and versatility

The Z Box S is designed for cyclists who want to free up their pockets and organize their equipment in a discreet and accessible way. Ideal for bike commuting, training rides, gravel adventures or MTB sessions, it advantageously replaces the saddle bag for aerodynamic and aesthetic gains.
