Designed for use in the ENVE Storage Bay found within Fray & MOG downtube frame storage, the Cargo Bay Storage Bags allow stashing tools, air, tubes, and any other essentials to keep you riding. The bag has a pull tab for easy retrieval from within the downtube. In addition to the main zippered pouch of the bag, there are several smaller pockets that allow for contained storage of smaller items such as C02s or tire plugs.
