{"product_id":"specialized-tarmac-sl8-expert-bike-4","title":"Specialized Tarmac SL8 Expert 2026","description":"\u003cp\u003eNo bike is as fast as the Tarmac SL8, thanks to a combination of aerodynamics, lightness and ride quality previously thought impossible. After eight generations and more than two decades of development, it's not just the fastest Tarmac ever: it's the fastest road bike in the world. Are your legs ready?\u003cbr\u003eAerodynamics or lightness alone don't win races: what matters is speed. To achieve this speed, you need to create an uncompromising combination of aerodynamics, lightness, stiffness and shock absorption. Using complex simulations based on real-world data, the Ride Science Team verified that the Tarmac SL8 is the fastest road bike on any course: - 16.6 seconds faster over 40 kilometres of flat terrain, 128 seconds faster on the Milan-Sanremo course, and 20 seconds faster on the Tourmalet climb.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAERODYNAMICS\u003c\/strong\u003e\u003cbr\u003eWe use aerodynamics where it matters most, and in the process Specialised has created the fastest road bike ever - yes, even more aerodynamic than the Venge. The front end has been optimised for maximum advantage. The fork crown is positioned behind the front of the frame's head tube to offer much lower aerodynamic drag. Thanks to the new UCI rules, the SL8 was able to use the narrowest and most aerodynamic seatpost ever made, ensuring that turbulent air around the legs can flow more easily towards the rear of the bike.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLIGHTNESS\u003cbr\u003e\u003c\/strong\u003eTo create the Tarmac SL8 and build the most aerodynamic bike while meeting the minimum weight requirements imposed by the UCI, we drew inspiration from what we learned with the Aethos. The team created a 685-gram frame, 15% lighter than the Tarmac SL7 and lighter than any other World Tour bike*. We focused on achieving maximum lightness in the down tube, seat tube and rear of the bike, applying the lessons learned from the Aethos project. The frame's shapes respond so efficiently to stress that it was possible to reduce the thickness of the material, eliminating the superfluous. *Except for that time Kasper Asgreen raced with the 585-gram Aethos frame during a stage of the Tour.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRIDE QUALITY\u003cbr\u003e\u003c\/strong\u003eThe Tarmac SL8's stiffness-to-weight ratio is 33% better than the SL7. The Tarmac SL8 sets a new benchmark for handling: it is precise in the most demanding situations and responds immediately and efficiently to pedal input. While the areas that ensure power transfer and riding precision are stiffer than ever, the Tarmac SL8 is more comfortable in the saddle, filtering 6% more stress from the ground and allowing you to attack corners with a feeling of agility and balance that is unique in the world of road bikes. The new Tarmac SL8 retains the proven geometry of the SL7 model, with the same generous 32 mm tyre clearance, so you can use higher volume tyres when needed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBEYOND GENDER DIFFERENCES\u003cbr\u003e\u003c\/strong\u003eIn reality, there can be many more differences between two male cyclists than between a man and a woman. We design based on the individual, and the philosophy is simple: Don't create differences where there aren't any. Every rider, male or female, can take advantage of the benefits of the Tarmac SL8. It's time to move beyond.\u003cbr\u003eThe Tarmac SL8 Expert Di2 features Ultegra Di2 groupset, C38 tubeless-ready carbon wheels, SL7 stem with Specialised Expert Shallow drop handlebars.\u003c\/p\u003e\n\u003ch2\u003e\n\u003cbr\u003eTech spec\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eFrame\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFrame: Tarmac SL8 FACT 10r Carbon, Rider First Engineered™, Win Tunnel Engineered, Clean Routing, threaded bottom bracket, 12x142 mm thru axle, flat mount disc brake\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSuspension\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFork: FACT 10r Carbon, 12x100 mm thru axle, flat mount disc brake\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBrakes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFront brake: Shimano Ultegra Hydraulic Brake\u003c\/li\u003e\n\u003cli\u003eRear brake: Shimano Ultegra Hydraulic Brake\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDrivetrain\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eShift: Shimano Ultegra Di2 R8170, hydraulic disc brake\u003c\/li\u003e\n\u003cli\u003eFront derailleur: Shimano Ultegra Di2 R8150, braze-on\u003c\/li\u003e\n\u003cli\u003eRear derailleur: Shimano Ultegra Di2 R8150, 12-speed\u003c\/li\u003e\n\u003cli\u003eSprocket set: Shimano Ultegra, 12-speed, 11-30 teeth\u003c\/li\u003e\n\u003cli\u003eChain: Shimano XT M8100, 12-speed with quick release\u003c\/li\u003e\n\u003cli\u003eCrankset: Shimano Ultegra R8100. 52\/36 teeth\u003c\/li\u003e\n\u003cli\u003eBottom bracket: Shimano Threaded BSA BB\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWheels\u003c\/strong\u003e \u003cstrong\u003e\u0026amp; tires\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFront wheel: Roval C38, 21 mm inner width, carbon rim\u003c\/li\u003e\n\u003cli\u003eFront tire: S-Works Turbo, 120 TPI, folding tire, BlackBelt protection, 700 x 26 mm\u003c\/li\u003e\n\u003cli\u003eRear tire: S-Works Turbo, 120 TPI, folding tire, BlackBelt protection, 700 x 26 mm\u003c\/li\u003e\n\u003cli\u003eRear wheel: Roval C38, 21 mm inner width carbon rim\u003c\/li\u003e\n\u003cli\u003eTubes: Turbo Ultralight, 48 mm Presta valve\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCockpit\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eStem: Tarmac integrated stem, 6 degrees\u003c\/li\u003e\n\u003cli\u003eHandlebar: Specialized Expert Shallow Drop, aluminum, 125 mm drop x 75 mm reach\u003c\/li\u003e\n\u003cli\u003eHandlebar tape: Supacaz Super Sticky Kush\u003c\/li\u003e\n\u003cli\u003eSaddle: Body Geometry Power Expert\u003c\/li\u003e\n\u003cli\u003eSeatpost: S-Works Tarmac SL8 carbon seatpost, FACT carbon, 15 mm offset\u003c\/li\u003e\n\u003cli\u003eSeat clamp: Tarmac integrated wedge clamp\u003c\/li\u003e\n\u003cli\u003eSWAT: Stem-headset-spacer set for SL7 stem and Roval Rapide cockpit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eProducer's\u003c\/strong\u003e \u003cstrong\u003eweight\u003c\/strong\u003e: 7.18 (size 56)\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eProducer's\u003c\/strong\u003e \u003cstrong\u003enotes\u003c\/strong\u003e: depending on component availability, specifications are subject to change without notice.
