{"type":"firestarter.listing","listing":{"id":"lst_kk2rGijA","product_name":"Harness Straps","category":null,"description":"Add straps to your handlebar harness - either ultralight TPU or even-lighter, USA-made Austere Mfg Cam straps!\nWhich one to pick? The TPU straps are our recommendation for most users. They provide a bit more stable ride than the Austere straps, because the stretchiness allows you to get more tension onto the strap.\nThe Austere straps are super tough and made-in-the-USA! They will be more durable with super heavy loads (anything over 6 lbs). The cam buckles are machined in Washington state, and then we add the straps in our Flagstaff workshop. They're also a bit lighter and save about 10 grams compared to the TPU, and are slightly longer for a better fit with wider-diameter dry bags.","images":["https://cdn.shopify.com/s/files/1/0610/6529/8090/files/rpgp-straps-28in-2pack-landscape.jpg?v=1761685810","https://cdn.shopify.com/s/files/1/0610/6529/8090/files/austere-mfg-buckle-straps.jpg?v=1763507152"],"price":20,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:43.062Z"},"share_url":"https://firestarter.network/l/lst_kk2rGijA","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
