{"type":"firestarter.listing","listing":{"id":"lst_xhZ8IPz8","product_name":"Kaibab Cradle","category":null,"description":"The Kaibab is a steerer-tube mounted harness unlike any other! Made from ultralight aluminum and carbon fiber, it mounts to a precision-machined 10mm headset spacer (included). The result is a cradle that is super convenient to use and holds your dry bag as close to your head tube as possible!\nUnlike other steerer tube mounted harnesses, you only have to install the Kaibab spacer once. Then it can stay on your bike full-time, and you can install and remove the cradle as needed, with just four bolts and no additional headset adjustments. Extra spacers are available, so the same cradle can swap easily between multiple bikes.\nOn bikes with long stems (most drop bar bikes), the Kaibab also holds your load significantly closer to the head tube than a handlebar-mounted harness. That means more steering stability. Bonus, it frees up that coveted handlebar mounting space for aero bars or other accessories!\nNote: The Kaibab will not work on every bike with front suspension, due to potential interference with the fork arch at full compression. If using a suspension fork with a forward-facing arch, it is mandatory to check clearance before you ride! We recommend using our fit calculator below before purchasing.\nUltralight Strap Options\nJust like the Blue Ridge, the Kaibab uses our special TPU bridges to hold straps onto the top carbon rod. These means you can use any straps you like, including TPU straps, without having them slide around or fall off the harness when not in use.\nWe offer two lightweight strap options:\n\n\n28\" TPU Harness Straps, which are 30% lighter than comparable straps\n\n31\" Austere Mfg Buckle Straps, with super strong USA-machined aluminum buckles.\n\nNeed help deciding? The TPU straps are a bit more stable and easier to use. The Austere straps are ridiculously strong, slightly lighter, and their 31 inch length will fit larger diameter dry bags.\nSpecs\n\n\n\nWeight\n7.5oz/210g\n\n\nLoad Limit (Road)\n10 lbs/4.5kg\n\n\nLoad Limit (Gravel or MTB w/suspension fork)\n7.5 lbs/3.","images":["https://cdn.shopify.com/s/files/1/0610/6529/8090/files/kaibab-cradle-with-included-spacer.jpg?v=1765588030","https://cdn.shopify.com/s/files/1/0610/6529/8090/files/kaibab-cradle-on-bike-side-view.jpg?v=1765588030","https://cdn.shopify.com/s/files/1/0610/6529/8090/files/kaibab-cradle-spacer-on-bike.jpg?v=1765668587","https://cdn.shopify.com/s/files/1/0610/6529/8090/files/kaibab-cradle-with-dry-bag.jpg?v=1765668587"],"price":185,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:43.050Z"},"share_url":"https://firestarter.network/l/lst_xhZ8IPz8","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
