Here are the four touring system items: - APIDURA Expedition Saddle Pack (17L) - MINOURA Seat Bag Stabilizer - BLACKBURN Outpost Cargo Cage x 2 In addition to the 17L saddlebag, by combining the seat bag stabilizer and outpost cages, you can attach items like a sleeping bag to both sides of the saddlebag. *It is recommended to put sleeping bags, etc., in dry bags. By using this system, you can load a large amount of luggage onto a road bike without using a carrier. In fact, I used it for a two-week camping tour in Hokkaido and was able to ride comfortably without carrying a backpack. Regarding the condition of the items, they have been used, so there is a feeling of use, but I think they can still be used. There is a small tear in the part of the saddlebag that touches the seat post, but there is no major damage otherwise. Please feel free to ask if you have any questions.
