The ORTLIEB Toptube Frame-Pack is a clever solution for utilizing the main triangle of your bike frame for storage without sacrificing your water bottle. This design is particularly useful for full-suspension mountain bikes with limited triangle space. With a 4-liter capacity, it offers ample room for heavy gear like tent poles and tools, contributing to a lower center for improved riding performance. The waterproof nature of the bag and its Tizip zipper allows for worry-free river crossings during bikepacking tours. Easily attached to the top tube and seat tube with Velcro straps, it is ideal for bikes with limited triangle space, and features a reflecting logo for added visibility. It is suitable for carbon fiber frames and now comes in a black matte finish with the zipper on the right side and interchangeable, individually positionable hook and loop straps.
