{"type":"firestarter.listing","listing":{"id":"lst_lWsn7WRh","product_name":"Portage Pack","category":"standard pack","description":"The classic, resurrected! Originally designed for the Ron's Bikes/Crust Alumalith, this portage-style pack lends just enough room for the essential sundries while staying out of the way of your whirling knees. You can now (re)live the golden era when moms and dads everywhere stretched out over loooooong stems while wearing smooth pistachio-shell shaped chunks of foam on their noggins. If you have an A L U M A L I T H , here's how the sizing breaks down:\n\n\n\nAlumalith 16\"\n86 degrees\n\n\nAlumalith 18\"\n81 degrees\n\n\nAlumalith 20\"\n77.5 degrees\n\n\nAlumalith 22\"\n74.5 degrees\n\n\n\n \nIf you don't have an A L U M A L I T H , determine your fit by downloading this PDF. You can print it out and hold it up to your bike, or put that high school protractor to use for measuring your top tube/seat tube angle, and then make your selection accordingly!\n\n15oz Waxed canvas exterior\nZippered sleeve pocket on non-drive side\n200D nylon lining  \nFoam stiffeners in all panels\n#9 Ideal zipper with Nanosphere coating \nCapacity: 1.5 liters\n","images":["https://cdn.shopify.com/s/files/1/0511/1129/7224/files/Crust-X-Rons-Bikes-Alumalith-66.jpg?v=1700497294","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/Crust-X-Rons-Bikes-Alumalith-59.jpg?v=1695848824","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/Crust-X-Rons-Bikes-Alumalith-62.jpg?v=1695909224","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/Crust-X-Rons-Bikes-Alumalith-79.jpg?v=1695909224","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/Crust-X-Rons-Bikes-Alumalith-80.jpg?v=1695909224","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/IMG_8549.jpg?v=1736870979","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/portage_pack_1.jpg?v=1736870979","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/portage_pack_2.jpg?v=1736870979","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/DSC05018.jpg?v=1736870979","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/DSC05019.jpg?v=1736870979","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/DSC04981.jpg?v=1736870979","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/DSC04986.jpg?v=1736870979","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/DSC04993.jpg?v=1736870979","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/DSC04996.jpg?v=1736870979","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/DSC05047.jpg?v=1736870979","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/DSC05045.jpg?v=1736870979","https://cdn.shopify.com/s/files/1/0511/1129/7224/files/DSC05001.jpg?v=1736870979"],"price":134.95,"currency":"USD","in_stock":true,"inventory_qty":219978,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:43.481Z"},"share_url":"https://firestarter.network/l/lst_lWsn7WRh","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
