This means your bags will be more durable in muddy and dusty environments.\nNeed help deciding which shape is best for your bike? Click here to download our printable guide that you can hold up against your frame to check the best fit.\nSpecs\n\n\n\nShape\nVolume (liters)\nVolume (Snickers)\nWeight\n\n\n90-Degree\n0.9 liters\n8\n4 oz\n\n\nGusset\n0.8 liters\n6\n\n4 oz\n\n\n\nObtuse\n\n0.8 liters\n\n6\n\n\n4 oz\n\n\n\n\nAcute\n\n0.8 liters\n\n6\n\n\n4 oz\n\n\n\nXL\n1.2 liters\n11\n5 oz\n\n\nXL Gusset\n1.1 liters\n10\n5 oz\n\n\n\nBehind the Name\n\nAll of our bags are named after sections of the Arizona Trail, which runs within a mile of our workshop in Flagstaff.\nRincon Valley is a section of singletrack where you can ride through cactus and mesquite with views of the Rincon Mountains in the distance.","images":["https://cdn.shopify.com/s/files/1/0610/6529/8090/files/rincon-90-degree-ultra-200x-black-magic.jpg?v=1751322726","https://cdn.shopify.com/s/files/1/0610/6529/8090/files/rincon-inside.jpg?v=1751322726","https://cdn.shopify.com/s/files/1/0610/6529/8090/files/rincon-acute-ultra-200x-black-magic.jpg?v=1750273808","https://cdn.shopify.com/s/files/1/0610/6529/8090/files/rincon-gusset-ultra-200x-black-magic.jpg?v=1750273808","https://cdn.shopify.com/s/files/1/0610/6529/8090/files/rincon-obtuse-ultra-200x-black-magic.jpg?v=1750273808","https://cdn.shopify.com/s/files/1/0610/6529/8090/files/rincon-xl-gusset-ultra-200x-black-magic.jpg?v=1750273808","https://cdn.shopify.com/s/files/1/0610/6529/8090/files/rincon-xl-ultra-200x-black-magic.jpg?v=1750273808"],"price":65,"currency":"USD","in_stock":true,"inventory_qty":59994,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:43.208Z"},"share_url":"https://firestarter.network/l/lst_2ociRirB","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
