To go cycling with the essentials at hand, the FRAME-PACK TOPTUBE 3L from Ortlieb is a small tubular bag that fits under the bike frame.

Offering 3 liters of storage volume, this tube-shaped bag has a low center of gravity on the bike, allowing for the storage of heavy equipment parts, such as tools, without being bulky. Combining a zipper and waterproof nylon fabric, this bag provides long-lasting protection for its contents, even in the worst weather conditions.

It is also very easy to assemble thanks to the sturdy, super-adhesive hook-and-loop fasteners that attach to the top bar of the frame, while variable side straps attach to the seat tube or down tube.
