{"product_id":"xds-x-lab-rt9","title":"XDS X-LAB RT9","description":"\u003cp\u003eThe XDS X-LAB RT9 represents the absolute pursuit of weightlessness in road cycling, engineered as the world’s lightest production carbon road bike frame. Born from an obsession with eliminating excess, the RT9 delivers a ride experience defined by effortless climbing, razor-sharp responsiveness, and pure efficiency at the highest level of performance.\u003c\/p\u003e\n\u003cp\u003eConstructed from an advanced blend of Toray T1100 and M40X carbon fiber, the RT9 achieves an astonishing frame weight of just 550 grams while maintaining the structural integrity required for elite competition. This ultra-light platform transforms every climb into an advantage, allowing riders to accelerate with minimal resistance and maximum control. The frame’s round-tube architecture reflects a philosophy of engineering purity, every line, every surface, and every detail exists solely to enhance performance.\u003c\/p\u003e\n\u003cp\u003eAt the heart of the RT9’s design is the concept of the “Shadowbox”. An invisible advantage that reveals itself through speed, efficiency, and precision on the road. Paired with a Shimano Dura-Ace Di2 drivetrain, the RT9 delivers instantaneous, precise shifting, while the Branta C50 ULR carbon wheelset with carbon spokes ensures exceptional stiffness, low rotational weight, and aerodynamic efficiency. A Branta carbon crankset with integrated power meter further elevates performance tracking, while integrated Apple Find My compatibility adds a layer of modern security.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame – \u003c\/strong\u003eXDS Carbon Frame, Toray T1100 + M40X, UDH Compatible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrivetrain – \u003c\/strong\u003eShimano Dura-Ace Di2 (RD-R9250)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheelset – \u003c\/strong\u003eBranta C50 ULR Carbon Rims \u0026amp; Spokes\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"XDS X-LAB","offers":[{"title":"Shadowbox \/ S","offer_id":47984862527733,"sku":"8753930816771","price":9150.0,"currency_code":"USD","in_stock":false},{"title":"Shadowbox \/ M","offer_id":47984862560501,"sku":"6753930816771","price":9150.0,"currency_code":"USD","in_stock":true},{"title":"Shadowbox \/ L","offer_id":48078554890485,"sku":"9250-00026","price":9150.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0483\/9040\/6312\/files\/XLABS_RT9_shadowbox_Contender_Bicycles.jpg?v=1776207168","url":"https:\/\/contenderbicycles.com\/products\/xds-x-lab-rt9","provider":"Contender Bicycles","version":"1.0","type":"link"}
