1.5L waterproof hard shell top tube bag with dual zips and layered storage—ideal for road, MTB, or commuting with zero leg interference while pedalling.
Built for cyclists who value structure, speed, and storage, this 1.5L hard shell top tube bag from ROCKBROS delivers a sleek, aerodynamic solution for everyday rides. The tough exterior shell resists impact and keeps its shape, while the narrow profile ensures your legs stay clear, even during fast climbs or tight turns.
Designed with practicality in mind, the bag features layered internal compartments that keep tools, snacks, and small essentials in place. The double-zip opening gives you full access without needing to unmount it, and a splash-resistant outer keeps contents dry through rain and grit. Reflective branding adds visibility in low light—an easy win for early starts or late finishes.
At just 300g, the bag fits snugly to your top tube with an easy strap system and doesn’t bounce or shift while riding. Whether you're commuting, training, or loading up for a gravel loop, this is the kind of bag you forget is there—until you need it.
