{"type":"firestarter.listing","listing":{"id":"lst_0OoMy-SK","product_name":"Mica Rat Tail Rear Rack","category":null,"description":"The Mica Rat Tail is an ultralight rear rack! Weighing in at just 410 grams including all mounting hardware, it blurs the lines between traditional heavy rack setups and ultralight bikepacking gear. Triple mounts on the sides will fit water bottles, cargo cages or anything under 2kg in weight that mounts to a 3-pack mount.\nThe Rat Tail mounts to your seat stays using heavy duty zip ties, and to your seat post or seat tube with a machined clamp. Shims are included to fit 27.2mm, 30.9mm, and 31.6mm seat posts and the clamp can fit directly onto the outside of many frames (as pictured on an Esker Hayduke).\nThe Rat Tail includes everything you need to mount it: Seat post clamp, shims, seat stay mounting blocks, and heavy duty zip ties.\nNotes:\n\nThe Rat Tail is not compatible with traditional panniers - although our Buckskin mini panniers will fit.\nThe Rat Tail is also not compatible with full suspension frames.\nOur price of $195 is a little more than the price on Mica's website, because we have already paid tariffs and shipping from Canada. The end cost to a US-based consumer will be less once those costs are factored in.\n\nSpecs\n\n\n\nTop Platform Length\n17\"/425mm\n\n\nTop Platform Width\n3.5\"/90mm\n\n\nMax Tire Size\n3.1\"/80mm\n\n\nWeight\n410g including mounting hardware\n\n\nWeight Capacity\n10kg/22lbs (2kg per 3-pack cargo mount)\n\n\nMaterial\n4130 chromoly steel tubing, 6061 aluminum seatpost clamp\n\n\n\n ","images":["https://cdn.shopify.com/s/files/1/0610/6529/8090/files/mica-rat-tail-rear-rack-2.jpg?v=1783627350","https://cdn.shopify.com/s/files/1/0610/6529/8090/files/mica-rat-tail-puck-attachment.jpg?v=1783621011","https://cdn.shopify.com/s/files/1/0610/6529/8090/files/mica-rat-tail-side-view-2.jpg?v=1783627351"],"price":195,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-07-09T21:59:16.843Z"},"share_url":"https://firestarter.network/l/lst_0OoMy-SK","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
