Both the Arkel Catrike "Trail" and "Expedition" bags fit the Musashi. The Expedition bags completely fill the rear frame triangle, while the Trail bags only partially fill them. I have the Trail bags installed on my Musashi, and they provide plenty of storage for tools, small Camelbak, wallet, phone, etc.
