{"type":"firestarter.listing","listing":{"id":"lst_d7R05pgR","product_name":"Handlebar Bag - UltraGrid Black","category":"Handlebar Bag","description":"In 2016 we released our original handlebar bag. It won awards, toured the world, and carried a bazillion calories. Now it's back with every detail refined to be the best bar bag for your gravel bike, road bike, or flat bar bike.\n\nThe bar bag features three cargo pockets, perfect for on-the-go storage, an interior zipper pocket with an integrated key clip for added security, and a phone holster designed for quick access. The bag is crafted from Challenge UltraGrid™ 100% recycled fabric and treated with a PFC-free DWR. With a 3.1L internal capacity, it's spacious enough for your essentials and then some. For convenient attachment to your bike, we include your choice of 6\" or 9\" Voile straps that run through adjustable attachment points, complemented by a rear cord, ensuring a secure fit. We recommend 6\" straps for most handlebars. If you have extra large-diameter handlebars (like flattened aero tops) we recommend the 9\" strap. All photos are of the 6\" straps.\n\n\n\n\nInstallation instructions here. \n\n\n","images":["https://cdn.shopify.com/s/files/1/0847/5984/files/Ultra_grid_black_bar_bag_studio_6.jpg?v=1772497275","https://cdn.shopify.com/s/files/1/0847/5984/files/Ultra_grid_black_bar_bag_studio_7.jpg?v=1772497275","https://cdn.shopify.com/s/files/1/0847/5984/files/Ultra_grid_black_bar_bag_studio_1.jpg?v=1772497298","https://cdn.shopify.com/s/files/1/0847/5984/files/Ultra_grid_black_bar_bag_studio_8.jpg?v=1772497298","https://cdn.shopify.com/s/files/1/0847/5984/files/Ultra_grid_black_bar_bag_studio_15.jpg?v=1772497275","https://cdn.shopify.com/s/files/1/0847/5984/files/Ultra_grid_black_bar_bag_studio_3.jpg?v=1772497275","https://cdn.shopify.com/s/files/1/0847/5984/files/Ultra_grid_black_bar_bag_studio_2.jpg?v=1772497275"],"price":86,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:39.837Z"},"share_url":"https://firestarter.network/l/lst_d7R05pgR","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
