{"product_id":"tarmac-sl8-pro-shimano-ultegra-di2-1","title":"Tarmac SL8 Pro - Shimano Ultegra Di2","description":"The Tarmac SL8 is the result of over two decades of development across eight generations, combining aerodynamics, lightweight construction, and ride quality to create the world's fastest race bike. Through race simulations using real-world data, Specialized's Ride Science team has proven the Tarmac SL8 delivers measurable speed advantages: 16.6 seconds faster over 40km, 128 seconds faster over Milan San Remo, and 20 seconds faster over the Tourmalet climb.\n\nAerodynamic design is integrated throughout the frame, with the new Speed Sniffer nose cone and a repositioned steer tube creating the sharpest, lowest-drag head tube shape ever. The narrowest, most aerodynamic seat post ensures clean airflow around the legs. The frame achieves an incredibly light 685 grams—15% lighter than the Tarmac SL7—while maintaining full aero capability at UCI minimum weight.\n\nThe Tarmac SL8 delivers a 33% improvement in stiffness-to-weight compared to the SL7, resulting in a stiffer pedaling platform and more precise handling at the bars. The frame provides 6% more compliance in the saddle, floating over rough roads with a supple feel unique among high-performance race bikes. The proven geometry and 32mm tire clearance are identical to the SL7, allowing easy adaptation and versatility for higher volume tires.\n\nThe Tarmac SL8 Pro comes fully equipped with a Shimano Ultegra 8100 series Di2 groupset featuring a power meter, Roval Rapide CL III tubeless-ready wheelset, and Roval Rapide cockpit, ready to race out of the box. The integrated 4iiii power meter includes Apple Find My technology, allowing riders to track their bike's location.\n\n\u003cdiv data-section-type=\"features-triple\" data-theme=\"\" data-text-align=\"left\"\u003e\r\n\u003cdiv data-section-type=\"feature\"\u003e\r\n\u003ch3\u003eAERO IN EVERYTHING\u003c\/h3\u003e\r\n\u003cp\u003eAfter a decade of working in the Win Tunnel, our engineers put aero where it matters, not just where it looks good. The result? A new Nose Cone called the ‘Speed Sniffer’ helps the new Tarmac SL8 be 16.6 seconds faster over 40km than the Tarmac SL7. And yes, more aero than the Venge.\u003c\/p\u003e\r\n\u003cimg src=\"https:\/\/assets.specialized.com\/i\/specialized\/Road-5758_Tarmac%20SL8_Article%20Tile_580x618_01?fmt=auto\u0026amp;w=1200\u0026amp;q=80\" alt=\"AERO IN EVERYTHING\" style=\"width:100%;height:auto;\"\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv data-section-type=\"feature\"\u003e\r\n\u003ch3\u003eMinimum Weight, Maximum Aero\u003c\/h3\u003e\r\n\u003cp\u003eWe saw how the lightest production road bike in the world - the Aethos -  could marry blistering response in the mountains with a supple, all-day ride.
