{"product_id":"factor-o2-miami-blue-50cm-2020","title":"Factor O2 Miami Blue - 2020, 50 cm","description":"\u003cp\u003eThe 2020 Factor O2 Miami Blue is a world-class, ultra-lightweight climbing superbike designed to deliver ruthless acceleration on steep alpine passes and razor-sharp handling on technical descents. Originally retailing for $8,000, this 50cm frame size is perfectly optimized for a nimble driver profile, comfortably fitting riders between 5'0\" and 5'6\". Draped in a striking Silver and Miami Blue team livery, the legendary O2 chassis features an incredibly advanced carbon fiber layup that trims the bare frame down to a featherlight 740 grams, allowing this complete build to scale in at a breathtaking ~15 lbs.\u003c\/p\u003e\n\u003cp\u003eThe electronic infrastructure balances pure competition performance with seamless ergonomics, anchored by a 2x11-speed Shimano Ultegra Di2 drivetrain. This electronic setup supplies instantaneous, crisp gear changes at the touch of a button, driving a versatile climbing package that matches a compact 50\/34T chainring configuration to shorter 160mm crank arms—an outstanding upgrade for an aggressive, high-cadence spin on smaller frame geometries. Stopping power is managed by lightweight Shimano Ultegra rim calipers, keeping the bike remarkably minimalist, aerodynamically clean, and easy to maintain.\u003c\/p\u003e\n\u003cp\u003eThe rolling stock introduces a premium, pro-tier factory elevation courtesy of a Black Inc Thirty carbon wheelset. These 30mm deep carbon hoops balance structural stiffness with crosswind invisibility, wrapped in top-tier 26c Vittoria Corsa PRO tubeless-ready tires to establish a fast, incredibly supple contact patch with the pavement. The zero-compromise specification is beautifully rounded out with a premium, one-piece integrated Black Inc carbon handlebar and stem cockpit (380mm width \/ 90mm stem), a matching Black Inc carbon seatpost, and a short-nosed Specialized Power saddle. Arriving in great condition, fully inspected, and certified by a master technician, this ultra-light Factor O2 displays only minor, honest cosmetic surface scratches from routine use with absolutely zero crash history, making it a turn-key dream build ready to scale your next peak.\u003c\/p\u003e","brand":"Factor","offers":[{"title":"Used","offer_id":45415113556015,"sku":"1310","price":2950.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0599\/6272\/0303\/files\/factor_o2_blue-1.webp?v=1780522692","url":"https:\/\/lebelbicycles.com\/products\/factor-o2-miami-blue-50cm-2020","provider":"Lebel Bicycles","version":"1.0","type":"link"}
