Fietstas Rockbros model met 1,7 l inhoud, telefoonvak, zwart

Rockbros bike frame bag with 1.7 L capacity and a dedicated phone pocket is a compact storage solution designed to attach to the bicycle frame. The low-profile black design keeps items close to the bike’s center of gravity and provides easy access to essentials such as a smartphone, keys, wallet and small repair tools during rides. The bag is intended for urban commuting and off-road trails where a minimal, secure storage option is required.

Advantages

The bag’s streamlined shape reduces wind resistance and does not interfere with pedaling or steering. A dedicated phone pocket helps keep the device protected and accessible while riding. The 1.7 L internal volume accommodates multiple small items without adding bulk, and the close-to-frame mounting improves balance and stability. Durable materials and reinforced seams provide reliable daily use, while the black finish resists visible dirt and matches most bike styles.

Suitable for

• Commuting and city cycling where quick access to phone and wallet is needed
• Day rides and short touring to carry tools, spare tube and energy snacks
• Trail and mountain biking when a low-profile storage solution is preferred
• Bikepacking setups that require compact frame-mounted storage

How to use

Place the bag on the main triangle or top tube of the bicycle frame and secure it with the supplied straps or attachment system so that it sits snugly against the frame. Store your phone in the dedicated pocket for quick access and use the main compartment for keys, wallet, multi-tool, CO2 cartridge or spare tube. Ensure straps are tightened to prevent movement during rough terrain and periodically check attachment points for wear. Close zippers fully before riding to protect contents from dirt and moisture.

Recommendations

For balanced weight distribution, avoid overfilling the bag and place heavier items as low and centered as possible. Regularly clean the exterior and inspect seams and fasteners to maintain durability. If riding in heavy rain, consider an additional waterproof cover or store moisture-sensitive items inside secondary waterproof pouches.
