Rockbros C40 bolsa de bicicleta bajo el sillín - negra

Most saddle bags are soft, shapeless pouches that flop against the seatpost and soak through in the first downpour. The ROCKBROS C40 takes a different route: a rigid, aerodynamic shell that holds its form, shrugs off road spray, and keeps your essentials exactly where you put them. It mounts under the saddle in seconds with hook-and-loop straps, no tools needed, and stays put over rough pavement thanks to an anti-shake design.

Highlights

• Hard EVA shell with PU leather finish resists scratches, impacts, and light rain
• Waterproof zipper and water-resistant construction protect tools, tube, and phone
• Reflective ROCKBROS logo adds low-light visibility for safer commuting
• Integrated tail light hanger lets you attach a rear light for extra safety
• Internal mesh pocket keeps small items separated and easy to find
• Universal fit for most bicycle saddles with tool-free installation

In daily use

Slide a spare tube, tire levers, CO2 inflator, and a mini tool into the 1-litre main compartment. The mesh pocket holds a patch kit or keys without rattling. The hard shell prevents the bag from sagging into the wheel or swinging on rough trails. When you finish a ride, the zipper opens wide for quick access, and the whole bag wipes clean with a damp cloth.
