Bicycle Frame Bag RockBros 1.1L Waterproof Hard Case Black

RockBros Twarda torba rowerowa wodoszczelna mocowana na ramę 1.1L czarna ROCKBROS is a compact, hard-shell waterproof frame bag designed to attach to a bicycle frame. With a 1.1 litre internal volume and a rigid outer shell, the bag provides a stable storage compartment for small items such as a phone, keys, wallet, multi-tool or energy bars while cycling. The waterproof construction helps protect contents from rain and road spray.

Advantages

The hard-shell design maintains shape and prevents crushing of contents during rides. Waterproof materials and sealed seams reduce water ingress in wet conditions. The compact 1.1L capacity balances storage space with a low-profile fit on the frame, preserving clearance for pedaling and handling. Attachment straps secure the bag to the frame to minimize movement and noise while riding.

Suitable for

• Commuting with essential items
• Road cycling where low-profile storage is needed
• Gravel and light touring for small repairs and snacks
• Urban rides in varying weather conditions

Key specifications

• Capacity: approximately 1.1 litres
• Outer construction: hard shell for shape retention

How to use

Position the bag within the main triangle of the bicycle frame and fasten the attachment straps around the top tube and down tube or seat tube as appropriate for your frame geometry. Ensure the bag is tightened to prevent shifting, then place items inside, keeping heavier items low and centered to maintain balance. Close any zippers or fastenings fully before riding to keep contents secure and protected from water.

Usage recommendations

Regularly check strap tension and attachment points before each ride. Wipe off mud and dirt after wet rides and allow the bag to dry before long-term storage to maintain waterproof performance. Avoid overfilling beyond the intended capacity to prevent stress on seams and closures.
