Reviews & Ratings
The ROCKBROS Bicycle Tube Bag is an integrated hard shell bag combo from AliExpress, praised for its 3D stiffened structure and flush frame fitment that looks clean and aero. It is priced around £20-40 GBP. Users report that the frame bag fits well but has a manufacturing defect where the zip side is cut or bonded slightly off, causing creases or undulations that spoil the look. The top tube bag uses only Velcro, no bolt mounting, and the zippers are considered poor quality. Some users managed to fix the issue with duct tape and plastic card. The bag is waterproof, but creases when empty.
